I ran across this 2020 D nickel in a roll i got from the bank. The Reverse on the word Monticello the M both o 0's the N and one of the L's appears to have some doubling. I don't know if it is machine doubling or doubled die. I'm sorry but those are the best pictures my camera will take. Sorry to bother you guys because i know you are busy with other more important questions. So I limit what I post and only post when I'm not sure about something. Thanks for you time.
