Buddy Rest in Peace United States 7075 Posts	Posted 08/15/2011 4:52 pm I showed the pictures and posts to my DH. He's in engineering and has worked with solvents and stuff. He says it looks like damage from a wire brush -- a hand-held brush that has wires going in every direction. I'm beginning to think that the coin was found encased in something -- like concrete -- and then cleaned. It is a puzzle! Report this Post to the Staff

I really can't see how any Acid, glue, samdblasting, etc. could do the doubling effect on the lettering though. Even any type of wire cleaning would not account for that effect.

Buddy Rest in Peace United States 7075 Posts	Posted 08/16/2011 11:53 pm just carl -- I know what you mean. It makes me wonder if it was an error coin that got damaged. I do like a puzzle and I just keep thinking about this coin...could it have been somewhat melted while it was somehow stuck in something like a cement block? Can't imagine how hot it would have to get though. Or maybe it got stuck in concrete and somebody used acid to get the concrete off of it... still it is so evenly damaged that I think that could not be it. Report this Post to the Staff
merclover Bedrock of the Community United States 10635 Posts	Posted 08/18/2011 02:17 am I think it looks as if dipped into clear nail polish and then had a chemical reaction to something. I have seen a similar sort of distortion before on a coin that had clear nail polish applied as the base. Les Report this Post to the Staff

Buddy Rest in Peace United States 7075 Posts	Posted 08/18/2011 09:58 am Why would anyone dip a coin into nail polish? To make it shiny? If this appears to be an a-typical reaction to a chemical solution and nail polish was involved, then maybe it was dipped into the wrong kind of polish. About 15 or 20 years ago there was a brand call '30 Second' or something like that. It was supposed to dry very quickly and was not the same as most nail polishes. It was taken off the market because it contained toxic ingredients (tuolene?). Report this Post to the Staff

Les The main problem with attempting to figure this one out is the numerous differences in that coins appearance. On the Obverse, the top is rather clear. The bottom is all messed up. On the Reverse, same effect for clarity in top versus bottom. The the wavyness of the lines on that coin. Not easy to do this with any kind of dipping in anything. Yet the most puzzeling thing to me is all the doubling effects on everything. No matter how or what could cause one thing just doesn't seam like it could cause that effect.

merclover Bedrock of the Community United States 10635 Posts	Posted 08/18/2011 2:25 pm If clear nail polish was brushed on and some sort of chemical residue was on the surfaces of the coin (a cleaner perhaps)in uneven amounts, it would cause an uneven reaction. And/or, using a powerful hair drier at full blast would cause ripples too, and cause uneven drying of the nail polish. Les Report this Post to the Staff
