I am no expert but will give my thoughts. See all those lines above the letters? That is the telltale sign of a very worn/deteriorated die. Since there is only a DDO listed for the 1981P I'm going to say it is DDD. The E looks Interesting but, it could just be a trick of the light. I cannot really explain it w/o holding the coin myself.
The split serif looks good, but the doubling looks very flat and shelf-like and is not rounded and the same height as the rest of the letter.
Yes I know lol I've been holding on to all the coins I find hoping ill find one some day lol thank you very much for your help.
