1936 Plugged M In America?

I can't tell if the letter is a grease plugged issue or not, there is some damage to the area the M should me but I'm not seeing reminisce of an M. The rest of the devices don't seem worn really either which I would expect more wear if it was just from circulation. I'm not well versed with plugged letters etc so wanted to get a second opinion. I just though it was amusing because it united states' of A Erica, to bad the E isn't missing as well because then it would spell my name lol. Anyway what do you think plugged or circulated to nothing?







I know it's not in great shape but it's rare for me to find a half decent shape Wheatie from my cent rolls. This is from the first roll I opened out if my Lott for weeks,didn't expect to find more US cents.
