I found this in pocket change years ago.I have done some research, but did not find any real info on such a coin. It does not have any reeding on edge. I can see a P mintmark. and some faint lettering at rim. I do know it is a 1999 Connecticut state quarter from tree design on reverse. Any ideas on how it came to be or value?
Very interesting! I recall that someone posted a coin with similar attributes to yours, but alas, old age has set in and I can't remember what it was called. It is not due to a grease-filled die. Rather, it has something to do with the weakness of the strike (I think). Perhaps someone with a better memory will chime in and help you. Chris
To me the rim looks too full on both sides of the coin to be a die trial piece . . . my vote is struck through excessive grease.
You mean the rims are supposed to be full, as in exhibiting full reeding? I agree, and will backpedal from my original assertion that this looks like a strike through greased dies. I jumped to the conclusion that striking pressure was adequate, based on the relatively sharp edge interior to the rim, however that is not sufficient to reach such a conclusion. Live and learn.
Type 2 planchets have an upset edge, a rolled feature, but it is not well-defined, especially at the inside edge of the rim, where it meets the fields.
I don't understand what you don't understand. Do you mean, "Why is it necessary for a planchet to have an upset rim?" Chris
Sorry I was talking about the upset edge. The low pressure strikes I've seen all have the upset edge.
It is my understanding that the purpose of the upset rim is to make it easier for metal to flow outward toward the edge. Chris
I believe that is correct. Essentially, creating the highest part of the coin therefore being the first part of the coin to wear and extending the life of the coin, if I'm not mistaken.
Yeah - I understand that as now most of the die pressure will be to pushing the metal of the planchet into the relief areas of the coin. Plus I'm sure that prolongs die life! First time I remember the Government actually doing something to save the taxpayers some money! Although the penny (Lincoln cent) still costs almost 2 cents for them to mint it!
You could run a bio diesel for a good 10 miles on the amount of grease those dies had on them. Sheesh!
