Yes, that one would fall into the damaged category. Good rule of thumb to take from this for future reference: if it really really looks like somebody pounded it with a hammer, that's probably what happened.
If errors are of interest to you, then it would be in your interest to learn how a coin is struck. I am not an error guy and can tell you from a simple glance that dime has been beaten. When you learn how coins are made, then you also learn what cannot be accomplished by the minting process.... Like a beaten down dime.
I strongly agree with this. To answer your question directly OP, an error is something that happened to the coin before it left the mint. Once it has left the mint, anything that happens to it is damage or circulation damage. Coin collectors value oddities the MINT made, they do not value things people do to coins afterwards.
Poor baby. That one reminds me of the ones we would hold to the grinding wheel in high school shop class.
It looks just like one I found on etsy! It must be a legit error, as two of the same one means they were struck that way!!! Right? But seriously, don't look up error coins on etsy. 99% of them are damaged. https://www.etsy.com/listing/993063...=sr_gallery-1-38&organic_search_click=1&frs=1
I want learn more. So when I do come across one. I can uphold my knowledge and backup my statement better.
If its from an uncirculated roll, it probably is a mint error. However, if someone messed with it and then put it in an uncirculated roll experts here could tell.
Man thank you. I swear you have been the best help on here. Good help is hard to find. I give you a 5 star rating
