I came across this 2018 D nickel, mainly because I'm afraid to spend change until I've researched and magnified
It appeared to my very unprofessional eyes that there may possibly be DDO on the date, most notably the "2". I'm including pictures of obverse, reverse, cropped date from obverse picture and a magnified picture of the date labeled #4. The coin weighs 5.00gm. Please let me know what you think.
