Are you looking to make the copper green with a patina?

if so then try this, (Found online)hope it helps

solution
2 parts white vinegar, 1 1/2 parts non-detergent ammonia, 1/2 part non-iodized salt

clean the coin first
brush or spray the solution on the copper coin
then clean with a lemon dipped in salt
then wash with soap and water

do not touch with bare hands. The oils from your hands will make the patina not stick. By the next day there should be a good patina on your surface. You can spray with water to stop the patina process, but make it a gentle spraying.

Thanks for your advice.

Old copper coins generally turn dark brown, not green.

Urine is sterile, but unless I see some reason to do it, I think I'll pass, too.

The coin is gimmicked, and although I've been searching for an older version of the gimmick, I haven't found one for sale. I'm inquiring with Johnson to see how much it would cost for them to make one for me.

Liver of Sulphur will work. But make sure it's REALLY diluted or the copper will just turn black. Some experimentation will be necessary. Also, it stinks to high heaven

The best way to give a natural patina is to keep the coin loose in a pants pocket.

If you need to speed-up the process, you may also used a very fine grain sandpaper use to polish car body shop.

Soak it over about 24 hours in water with a teaspoon of Miracle Gro plant food. Take it out and let it dry in the Sun for a day. Then rinse.
