PMD - Post Mint Damage - Interesting.. Looking at the overall bad condition of the rest of this Cent it looks like the date took a hard hit. Most likely a 1975 Cent. The bottom part of the 7 looks like it was pushed to the left. There is no way they could mint a backwards or flipped 7 on any coin.
First, welcome to the neighborhood! I don't know how long you've been collecting coins, but there are some things that common sense tells you cannot possibly occur. An upside-down "7" would look similar to, but not exactly like, an "L". In this case, since it doesn't, you should start looking for a simpler answer. Since the coin has numerous other nicks & dings, wouldn't post-mint damage be more reasonable? Chris
Since that coin was struck from a die, every coin made by that die would have the backwards seven. Then for the die to be made that way, the hub had to have that error as well. That would mean every obverse die made by this hub would be backwards. That type of error would be well documented in the numismatic community. Think about the initial 2009 series $100 bill and the scope of that printing mistake. It's simply impossible to hide something like that.
