I have held it under a magnifying glass and every other idea I could come up with. I dug this up in my backyard, about 5 inches deep. I would consider this coin in very fine condition according to what I have been reading. It only appears to have a little dirt on it, and I don't want to try to clean it up anymore. Do you know if the 1916 no mint mark would have just a little blob where a mint marked coin should be? Everything else on this coin is very clear. I will take a picture of it the best I can, maybe someone on here can tell. This coin has been buried here for at least 22 years since I bought the house.
