wesley1969 New Member United States 38 Posts	Posted 11/09/2018 12:08 am Howdy to all. Two stumpers for me. First, a 1990 with a strange crack in the planchet (?). Faulty zinc sheet? Second, a 2011 shield cent that looks pretty shriveled/banged up. Devices fat/flat. Cautiously leaning toward PMD on this one due to the apparent extreme wear, but those folded over rims are throwing me. Been practicing with the new commie "coin microscope", hopefully the pics are sufficiently clear. Thanks in advance for any assistance on these. Report this Post to the Staff

spru Bedrock of the Community United States 12477 Posts	Posted 11/09/2018 01:25 am Hmmm...great questions. The 1990 is most likely a plating issue, whether it be the copper plating itself or effects of trapped debris between it and the zinc core. It almost looks like a die crack in the third pic, but it's in an odd place for that and the next pic shows there is more to it. The 2011 appears to be a Dryer Coin to me. That's the only reasonable explanation I can come up with. Sorry, I can't provide any more definitive answers.

wesley1969 New Member United States 38 Posts	Posted 11/09/2018 02:19 am Spruett001 I think you may be spot on with coin 2. Was leaning in the direction of a rock tumbler filled with beach sand myself....tamayta/tamahta, I reckon. Earle's treatise on Dryer Coins was more empirically sound than most of what comes out of my VA shrink's mouth (and he is, IMHO, quite unstupid himself). Thanks, that one's going into my PMD stock book as a reference specimen... Report this Post to the Staff

I suppose I could plant a coin or two in our dryer...

Errers and Varietys Bedrock of the Community United States 75314 Posts	Posted 11/09/2018 12:23 pm The first coin has a cracked Copper plating issue, while the second coin was most likely a Dryer Coin. The second coin is Post Strike Damage ( PSD). Errers and Varietys. Report this Post to the Staff
