Hey Switch, forget about that 2 cent piece for now lol It's that 1866 Indian that is a gem :drool: Here is a safe method to clean them without damaging them. It will get rid of all that dirt so you can see the patina that is left on them. I can tell from the picture that the '66 Indian will clean up nicely. Take one of those coins and get it wet. Then put a dab of hand soap (any gel type or dish detergent). Now get a toothpick (the thicker the better) and put it at a 45 degree angle on the coin and start to rub in circles aggressively. The wood is softer than the metal, so no scratching should happen. Get into every letter and detail on the coin. Be aggressive enough to loosen the dirt. Use more water and more soap as needed. Wash it off and see what dirt is left on it. This is a safe method to remove that dirt. try it on the other non key date Indian first. I think you will like what you see. If the coin is in nice condition under that dirt, then it will turn out beautiful. If it is junk under that dirt, then no amount of cleaning will make it better. let me know how it works for you. PM me if you need more info.
