I found some of them coin roll hunting. I think this 1945 penny is strike through wire. that I found in a bag of pennys. its by liberty the error. this 1988 penny I think its also struck thru something like a piece of wire. and it has a interesting rim on the front. this 1998 is maybe also struck through wire its by the America between the e and the r.
The 45 appears to be PMD, the 88 is a slight misaligned die strike MAD on the obverse and looks like a scratch on the reverse. The 98 appears to be a die crack. JMHO
