I have a 1959 D Lincoln with a strange straight leg on the final 9. See the attached photo of one with a regular 9 and one that looks more like the straight leg on a 7. Is this rare? And if so is it worth anything?
I see why you're saying that, and it certainly does look like it. But, that doesn't explain why the tail of the 9 looks so much different between the 2 coins.
This is a common occurrence, and it happens when the finger of a rolling machine clips a digit of the date or another device(often the "I" in "LIBERTY"). Bottom line is that it's simply damage.
No, it's damage. I don't have one because I don't keep them, but I've come across lots of them. This is one of the most frequent questions that comes up in error forums because people find them all the time and think they have an error.
Exactly as the others have said. Errors are caused from errors during the minting process. This was simply damage from after it left the mint by a bank coin-rolling machine. It is no different than if you damaged a coin with a hammer.
Anyone else found one of these like the one I have? I really don't believe it is damage. See attached closeup. It has no scratch or clip. The upper curel of the 9 is totally different from the curel of the first 9. The bottom leg is totally straight. Jallen said he believes this is damage and seen lots of them, but has anyone else found one of these? Maybe someone can send me one they have. I am looking for confirmation that it didn't come out of the die that way.
What is a rolling machine? And how does it damage a coin? Is there any ligature you can recommend to read up on this?
A coin rolling machine counts and then rolls coins in a wrapper. Spinning wheels push the coins through the machine as well as crimping the ends of the rolls. The crimper will sometimes run a ring around the face of the coin, causing the damage seen on your coin.
I have also seen these. The others are correct in their statements. It is not an error. Post Mint Damage. It has no value. I am a long time collector of error and variety coins and most of these guys that have answered you are very knowledgeable as well.
