mikediamond Pillar of the Community United States 2738 Posts	Posted 10/30/2022 6:55 pm The surface details are soft and absent in some areas. It's far too heavy to have been struck on a copper core. I have never seen a full diameter copper quarter that approached the weight of a normal quarter. While such an error is theoretically possible, this ain't it. Everything I see tells me it is a genuine quarter that has been monkeyed with or a struck counterfeit. There are plenty of copper 25c counterfeits from earlier years.

silviosi Pillar of the Community Canada 6244 Posts	Posted 10/30/2022 7:58 pm For ALLs: An quarter without clad must be around: 1 side missing = 4.96 gr 2 sides missing = 4.25 gr Report this Post to the Staff
mikediamond Pillar of the Community United States 2738 Posts	Posted 10/30/2022 8:30 pm Your numbers are wrong, Silviosi. A quarter clad layer weighs 1 gram. Therefore, a quarter missing one clad layer will weigh 4.67 grams. If missing both clad layers (i.e., struck on a copper core) it will weigh 3.67 grams. There are exceptions. If one clad strip ends prematurely in the rolling mill, the resulting blank will be close to normal weight. Every example I've seen of this rarer type features a taper. In fact, every clad tapered planchet error I've encountered is missing part or all of one clad layer. Error coin writer and researcher. Report this Post to the Staff
silviosi Pillar of the Community Canada 6244 Posts	Posted 10/30/2022 9:32 pm Thanks for precision MIKE. I give just mathematical calculus base on 25% clad, I do not have in my hand the Mint really specs. I will ask and put to all coins lover the exact numbers for all coins.

JimmyD Bedrock of the Community Canada 21614 Posts	Posted 10/31/2022 6:08 pm Quote: How can we test it to know for sure Go by the weights that Mike Diamond gave you. If it is missing the clad on both sides, it would weigh 3.67g Can't be any easier then that. Edited by JimmyD 10/31/2022 6:11 pm Report this Post to the Staff
