Was Wondering If Anyone Has Any Idea Why These Two Coins Might Be Underweight. There Is Not Nearly Enough Wear From Being In Circulation On Either Coin So That Cant Be The Reason. So Are These Wrong Planchets Or Something Else?


1962 D - 4.73g

1951 - 2.91g

Small cent 1856 - 1971 was 2 grains or +/- .13 grams
Small cent 1972 - 1982 was 1.9 grains +/- .12 grams
nickels 1855 - date 3 grains +/- .19 grams
Rest in Peace

As Chase pointed out, there is acceptable tolerances allowed. The stock plates from which the planchets are cut may be thick/thin rolled (by microns), the alloy mix may vary slightly with the different metal weight of ingrediments then wear factor, cockpit error(your scale)...put it all together and the variances are great. NBD (no big deal)...

Keep in mind that as a coin is circulated it can weigh less from coin wear.
