How do you folks go about finding a coin whose size closely matches that of different coins? For example, we know that a US half dollar is very close to an old English penny, etc...

The coin I need to match is silver, and 36.07mm, so I need non-silver (copper, brass, etc), and somewhere from 36 to 37mm (approx). Ideally, a cool, exotic-looking coin would be best, but I'll cros that bridge when I come to it.

I've tried using the Web, but there are far too many coin resources, and precious few of them are concerned with diameter. How do I find possible matches?

Thanks in advance for your help!

Jerry Mentzer has some copper coins of the size of a silver dollar on sale. I am sure someone could help you with the URL.

I found a special coin from the "Harry Potter's world" (a "Gringott's coin") which is 38mm and seems to be made of brass. I found it... in a Belgian magic shop.
PM me if help needed with that.

Thanks, Jonathan! It's a Canadian silver dollar (not a Loonie) I'm looking to match, and although the typical ones are smaller, the ones I'm using, apparently called a "specimen/proof", are the same size as a US dollar. Therefore, a match will be easy to find!

Good Morning,

What I have done in the past is search Ebay for a specific size coin.
A while back I was looking for a copper coin to make a C/S Coin but since I work with Morgans I needed it to be 38mm in size.
So I began a search on Ebay requesting information on all 38mm Copper Coins as they were listed for sale.
Every time such a coin was listed I was notified via email.
It took a while but eventually worked out.

I hope this helped a little.

Take Care,

Vincent
