Hey all. Found a nice 1968-D Lincoln memorial cent in a roll. If I am correct, the weight tolerance for copper cents (without regarding circulation wear) is 2.98g - 3.24g. I measured this cent multiple times and consistently got 2.97 grams. A few hours later, I doubled checked and it weighed around 2.96g, then I checked again and it weighed 2.98g. Obviously, a change in conditions seems to be changing the scale reading. However, 2.97 is slightly below that tolerance, and this coin has not seen much circulation, and almost certainly not enough to change its weight. I know that a hundredth of a gram is so minute that this coin is most likely not rare or valuable. How far out of the tolerance must a coin be to be considered a rolled-thin or a rolled-thick error? Thanks, SorenCoins.
Thanks! I appreciate the honesty. I never know how to store things like this. Would you put it in a plastic tube with others? Plastic or cardboard 2x2 flip? What do you keep things like this in?
Right. You are the expert in this area, but I assume you also would not consider this to be a true rolled thin planchet. Or is it rolled thin, just not thin enough to be a considerable error?
I wouldn't label it as a rolled thin planchet, as it's just too close to low-end tolerance to be significant in any way; and, it looks like a normal coin, so I don't think it would bring any premium on Ebay, example. (imo)
I really appreciate your input, as always. Your experience is incredibly helpful. I will probably keep it for its condition, and perhaps make a side note labelling it as "1/10 of a gram under low tolerance," since it really shouldn't be labelled as a rolled thin. Always thankful to hear your interesting insight and comments. Thanks again.
"That's 1/10th of a gram under the low tolerance." He made a typo, it's 1/100th of a gram under low tolerance. To really draw a premium for a rolled thin planchet it would need to be 3 /10th to 4/10th of a gram below low tolerance.
You're right. Surprised I didn't catch that one either. That is good to know, 3/10th to 4/10th of a gram. Thanks
