Hey guys,

I haven't touched my coins in a while (probably 9-12 months). They've been sitting inside leather wallets. They're now discoloured. I have since moved them into plastic coin sleeves to reduce further discolouring.

I would love to bring back some of their charm, but I don't particularly want to remove the patina if I can avoid it.

This image represents a single coin beside a copper coin. You can see the coin has a lot of brownish hue to it instead of its nice silver + dark grey look.

This image represents my Triple Threat; the coins have not not discoloured evenly, and (as you can imagine) will be problematic in performances.

I would love to hear any suggestions people might have to fix this.

Thanks,

Andrew

I know the method that I list following will be bad , but at least it works for me , I scrub the coins using soap and sandpaper gently . It removes oxide layers ( if any ) or colorings on it . There will be only little scratch marks since it's a genuine coin and it's only scrubbed gently ( harder if need be ) .

I've been using this method since a few years ago , and found that the scrubbed coins tend to become dirtier looking faster than usual coins , that's a disadvantage but it's a quick method to ensure same coloring or aging on all the coins that I'm using .

I would love too , to hear some better ways of doing this .

First I'd try just rubbing the surface with your fingers -- sometimes that's all that's needed to remove a thin layer of discoloration.
If you're removing dirt, I'd go with mild soap and a toothbrush (instead of sandpaper).

I'm not really sure what it is. Some were sitting in a "Tony Miller: Mobius Wallet" which is a leather wallet, and the inside is lined. Others were in a different Tony Miller coin wallet (lined with red material). So not sure where the 'dirt' came from. I guess it's just oil / residue from the leather / pouch.

I'll try just rubbing them, will probably try a micro-fibre cloth, will try toothbrush and some soap, and will report back.

If it's just oil and residue from the leather , it's probably very easy to clean with just a toothbrush and some soap . Good luck cleaning Smile

A can of Nev-r-dull, and just BARELY touch it on the coins, a super light touch or rub. It will remove the leather oxidation and leave the patina. Rub it the least bit aggressively and you will have a shiny coin and no trace of patina, so start slow. You may even wrap a small amount around the end of a toothpick and use this. It may help you keep control of your bigass out of control thumbs.
