I noticed you posted a lot of diferent topics about one coin. Please post info and pics about the coin in the same thread. That being said, I will repeat what I post here on your other threads.
The 1988 Penny that you have doesn't have a MM on it because it was minted at philly. The ding looks like PMD.
