I'm new to this, but I found several coins with the same issue(s) and was curious to know if I needed to try to keep them to sell or just let them go back to the bank. The first issue (I hesitate to call them errors, because I honestly don't know& 🤷 #8205;#9792;#65039;) is a circular pattern around the edges of the coin. I have found 4 total so far, 2 on the obverse sides and 2 on the reverse sides. The second issues seems to be a bit more common. It appears to look like "dental mold" trim. A series of patterned strikes (usually 2-5) sometimes once, but as many as 3 times on the obverse side of the coin. It may be a bit difficult to tell from my photos. Any information about these will be greatly appreciated!
