roach Valued Member United States 364 Posts	Posted 02/22/2012 8:22 pm My daughter was showing me her coin collection and I noticed a BU 1986 D Kennedy half was thinner than the rest. I weighed it on an electronic scale at my pharmacy and it was 11.19 Grams-- A normal one should be 11.34 grams so it is .15 grams light. It is BU so it is not from wear. Could it be a foreign planchet? Or is there this much variance between planchets? I have included pictures of both sides and a comparison of the thickness with another "normal" Kennedy half.

So for a heavier coin, I'd guess that's OK. Why would anyone take the time to fake a clad coin? Report this Post to the Staff

Looking at the rim is not the best judgement of thickness which can vary with striking pressure. A weak strike will produce a thinner rim while a strong strike will produce a thicker rim. For example, compare the rims of a proof vs. business strike. The proof rims will look thicker even though the coins weigh the same. Report this Post to the Staff
