tomchad Valued Member United States 63 Posts	Posted 03/17/2008 11:39 pm When I came across this coin last night I thought it was just a blank until I turned it over. My father remembers finding it in 1959 and putting it in a small jar with a bunch of other change where I found it again 49 years later. Could anyone explain how this was caused without the coin being mushroomed? Plus,was this common for the time of minting? Thanks, TOM RI Image Insert: Image Insert: Report this Post to the Staff

coop Bedrock of the Community United States 62064 Posts	Posted 03/18/2008 6:07 pm The reason we know it is not a mint error is this: When the blank was cut it was smooth on both edges(Type 1). Then the blank is put through an upset process that makes a rim on both edges (Type 2) Then the coin is struck with the dies and the coin is complete. With the reverse rim removed and devices, they were done after the coin was struck. Possibly with the above mentioned process, but the result is the same, it wasn't minted that way. (Post mint damage) Why would someone do this? To deceive others or another reason. To make a love token. This was done more so on 19th. Century coins. removing the the reverse and placing initials or events and kept for mementos. They usually used silver coins, but who know why they did it to a Cent? Only the defacer knows for sure. We can just speculate. Edited by coop 03/18/2008 6:39 pm Report this Post to the Staff

coppercoins Pillar of the Community United States 7629 Posts	Posted 03/18/2008 10:16 pm It weighs less than a normal coin - it was ground down. It might matter what it weighed if there was a chance it was something else. Report this Post to the Staff
tomchad Valued Member United States 63 Posts	Posted 03/18/2008 11:14 pm What are the weight parameters this penny should fall within? I may be able to weigh it tomorrow. If this is a ground down penny, which I am convinced it is, the person did a great job. After viewing the the blank side under 250X microscope I could not find any evidence of grinding or even polishing striations. Also, the direction of the grain matched the obverse. So, I guess I must have jumped the gun on this. Doesn't seem likely to have an accurate strike with a rim on the obverse and no reverse. I will post my results as soon as I get them. Thank you all for the great responses, TOM RI Report this Post to the Staff

tomchad Valued Member United States 63 Posts	Posted 03/19/2008 3:58 pm It weighed in at 2.85 grams, question answered. It only cost my dad a penny almost 50 years ago so no harm done. Thanks again for the replies. TOM RI Report this Post to the Staff
