It is possible this may be a real dropped letter coin . the messed up area above the T could have been a part of the debris that had the die clogged and remained with the T when the die become unclogged. this T looks to be the T from the word CENT on the reverse die. a error expert would have to examine the coin in hand to be sure if it is real or a fake.
But, you have to have a stamp set with the same font and size as what looks to be the T in CENT on the reverse. The mark above the T is a bit sketchy IMO, if you blow up your pic it almost looks like the top of another T.
The T is a pretty good match, but its that area above it that is questionable. Sent it off to Mike Diamond so I'll know for sure after he has a looksy...
I'm really sorry to hear that , I was hoping you had a real dropped letter coin. some folks will try to fake about anything and a in hand examination by someone that knows coins good is the best way to know for sure.
