What can I use to bring back it's real color it looks like it has mold or something on it. I don't have no idea what I can use to bring back it's real color back front and back.
Yuck.. Nasty. Try Baking soda paste. Just rub it good. They are only still worth 25 cents each anyway. Gold plated does not add value.
Just a marketing gimmick but honestly whats the point of doing the work?They will still be face and won't really make a difference if it was me just spend them.
You would have to break them out to treat them, so they are just quarters with a platting of ? If it is gold, it is so thin as to be worth almost nothing. I'd just leave them as is. Actually, I'd get rid of them altogether.
If you are going to open them up Bentley. Clean the coins, if not successful, keep the slab, spend the coins. My opinion only, good luck.
