John1 Moderator United States 56855 Posts	Posted 11/04/2010 6:14 pm Normal size. If it wasn't for the odd edge I would say it was definitely PMD, but the edge has me puzzled.The edge is sunked in like a clad coin that has been dipped in acid and only the copper got eaten away.

clairhardesty Pillar of the Community United States 1027 Posts	Posted 11/04/2010 10:00 pm It weighs too much to have had the copper removed or never plated unless there is something replacing it. A copper plated zinc cent should weigh 2.50 grams, which is what you said this one weighs. Without the copper (2.5% of the total weight) it should be 2.4375 grams, which a good coin scale should be able to differentiate. Report this Post to the Staff
biokemist6 Bedrock of the Community United States 12437 Posts	Posted 11/05/2010 10:58 am No, it does not necessarily weigh too much. A scale that only measures to 0.1 grams will weigh a range of 2.45-2.54g as 2.5 grams. The cents also have a tolerance of +/-0.1 grams, I personally have recorded Zincoln weights of 2.42-2.57 grams on a very accurate analytical balance. Report this Post to the Staff
clairhardesty Pillar of the Community United States 1027 Posts	Posted 11/05/2010 9:28 pm With that being true, what non-damaging test can we use to tell if a cent is missing its copper? If someone overplates a normal copper cent with an extra 1% of zinc, can we tell that it was done without doing any damage to the coin? Can you turn a normal coin into one that looks like it is missing its plating without being detected? The Heritage auction archives only have a few unplated cents but they sold for $23 (ANACS 1993 MS62 partial plate, some copper showing) to $70 (ANACS 1989-D MS64, no visible copper). Might be a cheap way to make some money! Report this Post to the Staff
