Hello, I found a 1945 Lincoln Cent and it is very odd. The R in Liberty looks like a backwards R. Also, the 5 in the date looks to be punched over another number maybe. There are some other strange things about it but those two stand out the most. What could cause this? Thanks.
The wave like surface off your coin prompts me to say that it was cleaned with a hi-speed electric wire wheel brush. Full coin photo may help verify its condition.
