What you have is a filled die, usually caused by a die having grease or some other substance filling in letters or numbers on a die prior to striking of the coin.
Welcome to CT!! As stated your coin appears to have a filled die error. This is actually fairly common and adds no value unless a lot of the devices are missing. It looks to have affected the word Trust as well. Looks like it almost took out the "TRUS"...I can barely make em out in the photo. Congrats on your 1st find! Gotta ask have ya checked for a CAM on the reverse?
