OldJoeClark Pillar of the Community United States 1260 Posts	Posted 12/01/2017 12:33 pm There is damage on the edge from 3-5 o'clock and that area has a brass/gold tint. The remainder of the edge has the copper look. The spot in front of the mouth appears to be slightly raised. The weight bounces from 5.4-5.5g which is slightly under spec. Your comments appreciated and thanks for looking. Report this Post to the Staff

Seems like a bit of a science experiment!

OldJoeClark Pillar of the Community United States 1260 Posts	Posted 12/01/2017 12:40 pm Thanks Spence. Acid was my first thought but when I saw the copper still around the edge, I had second thoughts. Lets see what others have to say. Thanks again. Report this Post to the Staff

Mark1959 Pillar of the Community 7234 Posts	Posted 12/01/2017 4:21 pm I just took a quarter out to my shop and hit it with the torches - obverse side I just heated till glowing, the reverse I left it a little longer and seems the nickle started to vaporize and the copper started bubbling Report this Post to the Staff

Clad quarter planchets do not deviate from the composition as what the mint has to use. Just like Liberty nickels up through the Jefferson nickels have been minted on the same composition alloy plantchets. Report this Post to the Staff
