Anything that would remove it would have to be corrosive itself, and the action would change the overall color of the coin to artificial in my opinion. You can see the corrosion focus in each spot, where the activity began. After your acetone rinse, if it is put into a good environment and holder, it will not progress. Jim
It is indeed corrosion. Many things can cause it to be spotty like this. I've even known coins to have been sneezed on and over time, a spotty corrosion can occur.
What;s on your coinis is called oxidation spots from the enviorment or not preserving the coin properly in a holder. This can be caused by many reasons humidity etc ,and it is a form of corrosion, but the correct terminology is oxidation spots or carbon spots I suggest to clean use warm vinega or sour milk it may do the trick JC
Vinegar? My cousin used vinegar on his coins, and they all came out looking like they were "cleaned". Are you sure?
Well it's not. It's uncirculated and a very nice example if not for the spots. I would not recommend vinegar. It will ruin the coin. Trust me I have tried it. Before you do anything, make sure to practice on worthless coins. My advice is to leave it how it is and sell it. P.S. I have never had any results with acetone. Keep your expectations low.
? So you mean like Canadian coins and such? Just kidding. How much do you think it's worth. I have soaked it in acetone, and now have it in a hard 2x2 holder.
Value around $10? Maybe a little more like $13 or something but not much... and the Canadian thing... that's cold...
best thing to do is get rid of it and move on to another coin. It happens, sometimes the best solution is to move on.
No I really do like Canuck coins. I have a lot of their coins from different yaers, it's just they seem to make really crappy pennies.
