Dearborn Moderator United States 96386 Posts	Posted 10/24/2022 6:47 pm Thanks for the extra images of the side for comparison. - to me it looks like it could be a quarter on half-dollar stock. If true, then congrats. Has anybody worked out that math problem yet? Collecting since 1972. Learning from then on "Tell me and I forget. Teach me and I remember.

mikediamond Pillar of the Community United States 2738 Posts	Posted 10/24/2022 9:36 pm The OP's quarter was struck on a planchet derived from rolled-thick quarter dollar stock. If it was half dollar stock, it would weigh around 7 grams (such coins do exist). Error coin writer and researcher. Report this Post to the Staff
Petespockets55 Pillar of the Community United States 5775 Posts	Posted 10/24/2022 9:55 pm The coin in question is only about 11.3% above normal weight so it's most likely just rolled thick stock, but ..... someone just had to ask the following: Quote: Has anybody worked out that math problem yet? (Bad Dearborn. You shouldn't be asking old farts to do high school math!) I think I have. The weight for a quarter planchet cut from half dollar stock should be 7.1 grams. (But without mint tolerances considered.) Area of a circle- .... A = 3.14 x R(Squared) Quarter: (R=12.13) Area= 462.02 Half: (R=15.305) Area= 735.52 (Very hard to write these equations without a numerical keypad.) 462.02 = X 735.52 = 11.34 g. 462.02 x 1134 g. = X 735.52 5239.31 = X 735.52 7.12 grams = X (Final Answer!) ps. I found a CoinWorld article on wrong stock coins and how to calculate them, after going through the exercise above. https://www.coinworld.com/news/us-c...ting-wr.html Words of encouragement are one of the major food groups. We need to consume them regularly to thrive and grow. Edited by Petespockets55 10/24/2022 9:58 pm Report this Post to the Staff
