I am trying to learn some history on my penny I recently stumble upon. It has several errors. Ragged fissures from mint company, dated 1947 and stamped 43 and 45 above the 1947, the e in One on the back is connected to a 7 in between the E in one and the T in cent, the T is also a J, there are blob spots and Lincoln looks evil. I have searched a whole day and haven't found anything on it. I also would like to know about a 2020 P mint nickel. The Monticello on the back has a Liberty Bell surround it as if it were there first and the Monticello was stamped over top of it
