Topic: Making your own coins
Message: Posted by: shelley1508 (Dec 28, 2008 12:53PM)
Hello everyone. I'm looking for any information or advice about making your own shell (and other more elaborate) coins. The world of lathes and machining is horribly complicated and daunting so if you have any kind of experience with them that you can share I'd love to hear from you.

I've asked a similar question at

http://www.themagiccafe.com/forums/viewtopic.php?topic=290712&forum=26&0

but have posted here, unsure which forum was more suitable. I realise that this is an unforgivable breach of forum etiquette. I do hope you don't feel too violated : )

Why would you want to? Quality gaffs are very affordable from Tango and Johnson. And if you count how many mistakes you will make getting experience in this fine art you will probably pay more for home made. I would guess that the machinery used to get the needed precision is also quite expensive.
I used to make my own card gaffs but that is much easier.

Thanks for replying! Although Tango do produce some good coins, the coin I need is fairly specific, and they don't stock anything like it.

Neither do anyone else, unfortunately. The other reason is that the coins are needed as part of an effect I'm developing (it's almost out, if any of you are UK-based and will be at the Blackpool convention then l'll be there), and I need high quantities (around 100 initially, perhaps more if it's successful). At £15-20 a time from Tango (even if they did stock anything similar) they would end up costing more than a lathe ...

I asked the same type of question before on making gaffed coins and got a heap of sarcastic replys. its hard for me being from Australia in obtaining Australia currency trick coins. currently having a go at making some trick coin with a scroll saw(using smallest blade) and a dremel cutting tool. with some great success. will send you some pics if you want. if you want to make a shell coin you could use a drill press and drill lots of small holes and hone the rest out using a dremel. or get a round cutting peice from your local hardware store and just drill one hole. you will need a good clamping device for both opions.

I think kcquinn50 is right about making lots of mistakes initially. But forums like this are helpful in that other people can let you know at least some of them before you start out ...

The dremel option sounds like it might work, but for lots of coins (and precision tolerances) it'll be a problem.

I'm looking to embed objects within the coin, so I need to machine a shell and lid. I'm guessing a lathe and some kind of holder or adhesive (I've heard that dopping wax is sometimes used to fix the coin in place) should be at the beginning of this hypothetical shopping list.

Someone should write a book on this ...
Message: Posted by: kcquinn50 (Dec 28, 2008 07:58PM)
Now you are getting me to think about it. But I don't want to DO it. Maybe small, low profile magnets to hold the lid in place?

If I was to try this, I would plan it out first and then have an experienced friend help with the machine work. I know some people that work at and/or own machine shops.

Here's an idea: The coin gaff makers could probably produce your quantities at an even cost, compared to you buyig machinery and/or paying a machinist. And if your idea is truly unique you could even market it - and get your money back.
Message: Posted by: shelley1508 (Dec 28, 2008 08:14PM)
Sadly the coins I'm using aren't attracted by magnets.

It's a good thought about the coin makers - but I'm trying to cut production costs as much as possible. The initial outlay doesn't matter so much.

Talking to an experienced machinist is a good suggestion. Perhaps one will come across this thread : )
Message: Posted by: kcquinn50 (Dec 28, 2008 08:24PM)
I meant glue small magnets to both halves so that the lid will stay on.
But then again I don't have an image in my mind of what you are trying to make.

A magnetic copper/silver set has the magnets inside, but if you have empty space inside, you may have room for very small magnets and still room to hold items. Keep the magnets around the perimeter.

Not too long ago somebody posted a link here of a site that sold "spy" coins. Real coins that could hold things inside. I believe they were from the U.S Mint.

I've tried that with my lath - and have to say, that this was not an easy job. The problem is, that first you need a pretty good holder for the coin (forget magnets etc.). The second problem is, that when it's getting to the end, the left over thickness (in the middle part) of the coin should and will be pretty thin - and if it's thin, it's weak - and then it's pretty easy, that the coin arch it's back due to the pushing of the lath tool (actually: same with a mill). So you can work very very slowly, but even then, it's hard to avoid this buckel, when you try it with big coins (small coins are way easier). So it's not a problem of the accuracy, but a problem of the buckle you might get in there. For me, I could get out some (a few) fine results, but I wouldn't do it again.

Anyway: I think it's possible when you work with a perfect fitted holder and very very slowly. BUT: If it's worth it, to spend hours and hours (think of 100 pcs - uhh) down there in the garage, you have to decide by your own. Before buying any equipment for this, I would go out and get some quotations of the well known manufactures !

Thanks for your answers. From searching through this forum I have a slightly better idea of what is needed - perhaps a taig lathe, cutting tools, internal micrometer, and a collet. I figure this would be enough to make a shell. However, I need to make a lid, which will require thinning down the coin to 1/2mm and then reducing the diameter slightly. The question is how you would hold the coin to do this, and how to stop it from buckling like Jogi says.

The other thing everyone seems to suggest is that I get an experienced manufacturer to make it for me. At the moment, that's working out ok for me, but it's costing around $20 to have each one made and as you can imagine, getting 100 done costs almost as much as buying all this equipment. I know it'll take a while to learn, but I have the time and I'm willing to put in the effort. I don't know anyone who'll teach me first hand, so posting here will, I hope, help me to avoid some of the more basic mistakes.

Man I was thinking hard about doing this and with all this info on cost and everything I think I will just hand my cash over to the experts and if I should ever get rich than I will buy a coin gaff company already set up. Wala end of problem.

So yea instead of buying your own, isn't there anyone in your area that you could lend you the time for the machinery like no more different from renting a sound studio to cut a track.

If I was going to make Gaff coins I would go back to college to do a engineering course.
Learn the correct ways of metal turning even using the college lathes to have a go see if it was something I could do.
If you learnt to use the lathes properly there would be endless list of tricks and gaffs you could make.

You have to invest in yourself but it will be worth it in the long run

I sometimes think you have to make a choice which is perform magic or make magic

Seems to me sarjito that you are well ahead of the curve on making gaffs. Your coins look pretty darn good to me. Others might tell you that you gotta do this and you gotta do that but sometimes you don't have too really. I mean it's not an easy job I'm sure but what you've done here looks as good as anything I've seen and way ahead of others that wanted to just try doing it. I'd say that you have the basic idea down. Bet a guy like Lassen or Schoolcraft would hire you to help with their stuff. You might not know all the specifics but at one time all these guys didn't know the specifics either and I'm not sure they are engineers. What they are is successful. Who knows might've learned it at home from their dads or something.

Anyway, keep up the good work. Keep trusting in yourself...I think you can do even more. ;)

What some don't seem to understand is that you have to start somewhere when learning how to do something. Everytime someone comes here asking for info on making or building certain items, you get those who try to discourage them. They say it isn't worth the time or money involved.

There is nothing wrong in asking but wanting to know trade secrets, source codes, intellectual properties, etc. just for the asking is a bit innocent let's say. If I went with that perception, I guess I could call the Pentagon's 800 number and ask for the nuclear launch codes of the day or call KFC and get the secret 8 herbs and spices.
And of course we have no background on this chap's experience with metal working. I don't know, would one have had a least some metallurgy classes? Hey, Roy Kueppers is in the latest issue of Reel Magic and talks about shells. Pick it up and get some actual working insight on this undertaking. Or just call Lassen, SchoolCraft, Johnson, Tango and say hi can you show me how you make gaff coins so I can make them myself. ok since I already painted myself as being such an a@@, here is something to chew on to understand the scope of making gaff coins- if your going to do, then do it *** it.
The Differences in Commercially Made Coin Gaffs:

Updated and revised for 2010
By Mark Reed aka Marc Mayhem of MagicVault With so many makers of coin gaffs, new magicians often find themselves wondering “who makes the better gaff?” or “What are the differences between all these guys?”. With exception to the high end custom makers such as Schoolcraft or Lassen, most coin gaffs are commercially produced using precision metalworking equipment in a mass production approach. Schoolcraft and Lassen are focused on custom work where each set of coins is treated as a unique process and even greater focus is given to the finer details. While custom makers offer the absolute best in quality, be prepared to spend hundreds of dollars on your gaffs. But what about those of us that just want an affordable gaff set to practice and learn with… do we need to give up quality fit and finish? The answer depends on what manufacturer you choose. We will highlight the most common makers of commercial coin gaffs and try to give an honest opinion of the pros and cons of each…
Johnson Precision Magic Coin Gaffs
Johnson has long been considered to be the best maker of commercial coin gaffs. They have been around for a very long time and have a commitment to quality that surpasses any other commercial maker. The fit and finish of their coins are so close to the custom makers that unless you are looking for special coins (antique silver dollars for example) Johnson is the way to go. I think you would have an incredibly difficult time finding any magician with something bad to say about Johnson products. The downside to Johnson is that not every magic shop carries them, and they are usually priced higher than most other commercial makers. Additionally, the flipper coins by Johnson seem to be subpar when compared to others such as Tango. MagicVault is proud to be a Johnson dealer and can supply you with any of their items. (Editors note: Link to Johnson Coins on MagicVault )

Tango Coin Gaffs
Tango is an Argentinean company that has recently gained more of a presence in the U.S. They offer a very wide selection of items. In fact, in addition to the common gaffs, they offer many unique items and gaffs that are exclusive to Tango. Many times these unique items are common gaffs tweaked in ways that the founder of Tango feels adds more value or ease of use. The quality of Tango items is very good. Not quite as good as Johnson. The fit and finish of the gaffs are of quality, but if you place them next to a Johnson, you will notice a difference. Sometimes the edging and milling is a little rougher, or there is a little more gap in a shell. Nothing major, but still a difference. Where Tango does fall short is the included instructions with gaffs. They are horrible. They are written in very broken English that often leaves unfamiliar magician unclear about the use or method of handling. If you order a Tango item, either know how to use it, or know that you can work with a fellow magician to get the

handling down. When I last spoke with Mr. Tango, I have been told they are working with English translators to improve the instructions for the English market. I have seen several items since then and they have indeed made vast improvements. The Tango Ultimate Coin is a great example of Tango at its finest. MagicVault does carry various Tango items we feel are of merit. We do not carry the entire line as we suggest magicians purchase Johnson where we see a quality difference. Pricewise, Tango is very close to Johnson – usually about 10-20% lower. I think as Tango becomes more aggressive, you will see them surpass Johnson.

Roy Kueppers Coin Gaffs
You occasionally find gaffs made by Kueppers. Kueppers is actually a custom maker but supplied gaffs commercially. These gaffs are well made. Kuepper also makes various coin utility items such as coin benders. Kueppers is on par with Tango and priced similarly. If you cannot get a Johnson or Tango, Kueppers is a decent alternative. Be careful as some dealers tend to sell Kueppers at a high price comparable to Johnson. Where Keuppers stands out is the gaffs he custom makes. Much lower price than Schoolcraft or Lassen – and very nice quality.

Sterling Coin Gaffs
You do not see Sterling too often these days. Due to the dominance of Johnson and Tango, Sterling has become a lesser known maker. Sterling offers a somewhat decent quality – but again a definite noticeable difference when compared among Johnsons. They are much lower in price, and do have a narrow product line that is mostly limited to shells and nested coins. For the cost, stick with one of the other makers. MagicVault does not carry Sterling at this time.

Sasco Coin Gaffs
Sasco gaffs are where you start getting into the low cost economy coins. Sasco, while inexpensive, often lacks the quality and detail fit and finish that working professionals and picky amateurs require. They are perfectly fine for beginners looking to get a few gaffs to learn and practice with, but in all honesty we suggest taking that money and putting towards one of the better made gaffs. The prices are not that much lower that it creates a huge spread. Sasco has been getting better at quality and hopefully they will grow to the point of being on the same level as the rest. Only time will tell.

No Name Makes
These are usually gaffs made overseas, or some of the SS Adams or Magic Makers gaffs. They are made in bulk lots in a very quick and sloppy manner. They often have rough edges, gaps in milling work, sloppy fit, etc. They look gaffed and spectators will notice. Stay away from the coin gaffs that are no name brand unless you need a very low cost gaff for occasional amateur use. Consider these practice sets.

Schoolcraft or Lassen
As we mentioned at the start of this article, custom makers are the absolute best in terms of quality fit and finish. Schoolcraft and Lassen are the premier makers of custom coins. Be prepared to spend a great deal of money – however you will have a gaff set that holds its value and performs flawlessly. If you are a working profession that relies on coin work and are making

a good living doing magic – these are for you. Amateurs with some extra cash and desire to have the best – take a look at them also. Anyone else – stick to Johnson. Johnson will not disappoint you. There are obviously other makers spread across the world that we have not touched upon. The goal here was to hit the mainstream and well known makers to help people understand the differences. Granted these comments are the opinion of MagicVault staff, we find that they mirror many of the professional views in the community. Folks, basically what it comes down to is that if you are a person that wants the absolute best (and you have the money available), go with Schoolcraft or Lassen. If coin work is your money maker and full time forte, by all means use the best out there! If you are happy with a quality commercial gaff and not looking to spend a fortune, go with Johnson or Tango. Johnson and Tango are professional level gaffs that have come a long way in the past years, gaining much respect in the magic community. These gaffs will last you a lifetime. Maybe people make a living off doing magic using Johnson and Tango items. That wraps up this attempt to give you folks out there in magicland a decent review of the major players in the coin gaff market.

It was a reasonably question. There are tons of people willing to share how card gaffs are made, so there is no reason you wouldn't think the same is true for coin gaffs (especially since few people have lathes and mills lying around).

But apparently it is not true for coin gaffers. Maybe make a friend in the milling business and they will have an idea (sorry, but I don't).

Message: Posted by: sanjaya (Jan 16, 2010 10:02AM)
I really don't know much about coin gaffs, but it's my understanding that expanded shells are expanded before they are cut. That is, they get smashed (a technical term) which makes them thinner and bigger in diameter. Then they are cut. Most are tails side for a couple reasons. One is that you don't have to match dates. The other has to do with the relief in the heads side can result in a thinner, weaker shell.

That's all I know about anything. And I might not even know that. Come to think of it, don't read this.
