Another person mentioned that it may be a lamination problem. I am not sure what he meant by that though.
I see nothing in the photos indicating lamination. I do see evidence of forceful sliding on a rough surface. Maybe someone decided to see if they could stop on a cent rather than a dime. Damage.
I can't say for certain what caused the marks on your coin, but I'm absolutely certain that it did not occur at the Mint. @paddyman98 and @desertgem are very knowledgeable about the minting process and have also said it is PMD
desertgem, Thanks, how would that cause the raised areas. I figured it is damaged. I was just trying to determine how the raising was caused.
Copper is very soft ( why damage occurs so easily ) and it is easy to push around with engraving tools, so whatever damaged this coin pushed it to be raised in an area. In the older days, some very talented engravers and other metal craftsmen could drill a hole on the edge near a date and insert a steel tool and push up copper to produce a desirable mint mark and then fill the hole. A 1909 became a 1909-S cent. I still check the edges of coins as well as both sides, to many they are not considered. There are few still alive today that skilled. Jim
desertgem, I had no ideea about that, great tidbit, Thanks. I do check edges mostly for lack of or missing reeding. I will be looking a bit closer at the edges for filled holes now. In my research I read that the mint struck coins for other countries, I had originally thought it may have been a foreign coin strike then a US strike. The part under the U looks like a large ear to me. It is a weird coin though. Good conversation piece.
ldhair, If it is then it looks and feels just like copper. I tried to wash it off with acetone yesterday when I washed my 40. It looks the same. I also sharpened a chopstick with a pencil sharpener to try and scrape it with no luck.
