Could it maybe be a Die Trail of some sort? I want to share this website with you -http://www.traildies.com/
Feed fingers would have gouged the struck coin. These are original and INTO the coin (if Sheila is correct and they are not raised). They look raised to me. They were on the face of the die (go under the letters). I'll bet they were on the planchet as I don't believe wide marks like this are made by any tool used to polish a die. When dies show this type of mark coming from the letters they are called "trail dies" but these do not appear to come from anything. Using just photos to determine their source, you have a neat mystery coin. Edit: Guess it is an abraded die.
The lines appear inside and outside of the bays. It looks like die scratches to me. Possibly linear plating bubbles?
They are solid and in the bays as well as through the top and bottom of the coin. They run exactly straight. They are not wavy at all. Smooth as well.
NO. Deterioration happens by itself as the die is used. It can also happen if a die is not stored correctly and deteriorates. Abrasion implies scraping/rubbing/scrubbing, & whatever - done by someone at the mint.
This is my opinion: In a perfect world, a coin like this would not occur. That is not the case. The Mint is a factory and all sorts of INSIGNIFICANT things can happen. The coin you posted here is neat. I wish it were mine; however, aside from going into a teaching set (for example) to show students what can happen at the mint, IMO, the coin is nothing special EXCEPT to those collectors who enjoy looking at coins under magnification. If I found it I should keep it in a little box with the rest of my "junk" with die breaks, die polish, cuds, laminations, etc. None of this stuff is worth much but I'll never part with it. The important thing is you are having inexpensive FUN, you have found some pretty good coins that you can sell for multiples of your cost, and you are learning about the basic numismatic characteristics seen on coins. I hope one day you have the chance to take an error/variety seminar as you will make a great student!
IMO, your coin is no longer insignificant. So, that means the feed fingers SCRAPED THE DIE right? Makes sense. I've never seen this before. How scarce is this characteristic? Does it happen more on one coin series? Value on a cent like this? Just looked up "die scrapes" on Error-Ref. it is in my favorites... Neat!
Quite common. On morgans at least. I'm sure they're just as common on modern Lincoln's too with the bazillion they pound out
Thanks, I've never, ever, seen this type of mark on a coin. I probably didn't have a clue what I was looking at if I did see one. I'm going to start a thread right now to see how common these are.
