Just found a 1955 wheat penny weighs 2.57 grams. I put it next to another 1955 and its HALF its diameter! It also makes a different sound when dropped. The coin is not very worn any ideas? ob3rst
Photos are too far away, but it doesn't look like an acid job from the first photo on the scale. Probably is a rolled thin planchet, which is very very common for that date. With normal copper cents weighing 3.1 grams, 2.5 to 2.6 isn't that thin, but it is thinner. Please post a set of both obverse and reverse, and we'll all be able to view them, and tell you exactly what you have there. My guess, from the far-away photo, is that it's rolled thin.
Post some pics closer up, cropped and posted full size and @Fred Weinberg might be able to tell you if it is worth some bucks.
so your telling me there is a chance, if you don't want to lose your two wheat cents ill send you 2 new ones, your are only hope
lol. What I'm telling you is that the guys who are helping you now, are much more knowledgable about coins than I am. Please listen to them , NOT to me. "...putting my two Wheat cents in. " is just a "play on words", as in That's just my 2 cents, which in American vernacular simply means That's my opinion.
Thin planchet would be a good coin. Also a greaser (LIBERTY) and this coin has seen heavy circulation. Don't clean it.
Roughly speaking, what's the percentage of planchets that are thin like the OPs coin in a given year?
That's impossible to know - except that 1955 is the most common year of this error. And, since they ended copper cents back in the early '80's, it's now an obsolete error type.
I usually put a “disclaimer” on my “opinions”. I like to put in a little research and see if I am right or need to do some more learning.lol I would get way too bored if not trying to contribute at all as I don’t get very many new or interesting coins of my own to research.
