I've seen some interesting bubble issues. I saw a Lincoln that looked like a very runny nose. They could be a part of a humorous collection I suppose. Not as great as a Morgan scarface, but....
The US Cent has never had a P mintmark except for an anniversary in 2017. A P mintmark was placed under the date.
thanks to all for the help am new to collecting really appreciate it. how bout on the quarters if one is missing the designers initials would that be an error or do they not put them on all either?
