OldJoeClark Pillar of the Community United States 1260 Posts	Posted 02/17/2017 10:53 pm I weighed this several times and compared it to other zinc cents and this one is over the 0.13gm tolerance. Your thoughts appreciated. Report this Post to the Staff

Fuzzy317 Moderator United States 14463 Posts	Posted 02/17/2017 10:58 pm Looks like there is glue or plaster below Lincoln's profile, and to the left of the Memorial and in some of the letters on the reverse, there appears to be dirt or something. This might account for the weight variance Report this Post to the Staff

OldJoeClark Pillar of the Community United States 1260 Posts	Posted 02/17/2017 11:09 pm Good eye Fuzzy317, I completely missed the junk in the rim. I did remove it and it still weighs 2.8. If I weight it several times, about every fourth go it comes up 2.7. Report this Post to the Staff

Garycrant New Member United States 26 Posts	Posted 02/17/2017 11:40 pm I have same scale. They're cheap and notoriously +0.1g. I have to Zero a few times per coin. Test it against a US bill (any denomination), they all are 1.0g as long as they're new w/o human hand funk. Report this Post to the Staff
OldJoeClark Pillar of the Community United States 1260 Posts	Posted 02/17/2017 11:55 pm The scale is inexpensive but has done very well for me. I put 5 different zinc cents on it and each weighs out at 2.5gm and when I throw this one on, it goes to 2.8gm. Zeroed it several times, repeat and get the same results. The max this coin should weigh is 2.63gm. I put a fresh bill on it and it weighed 1.0gm, just as you said. Report this Post to the Staff
spru Bedrock of the Community United States 12477 Posts	Posted 02/18/2017 12:25 am I use the same exact scale and have recently had to tare it more often and can get a range of 3/10ths for the same coin in a matter of minutes. This wasn't the case after I first bought it, just recently. I do believe you though OldJoe in your conclusions. It just reminded me I need to get a scale that does hundreths so I won't be confused by automatic rounding of tenths.

Conder101 Bedrock of the Community United States 17884 Posts	Posted 02/20/2017 12:04 pm Sounds like it is struck on a slightly thick planchet that is out of spec. A legitimate error, but a minor one. Report this Post to the Staff
