Lately I have noticed I have been getting some unusual TIDs that yielded surprises. One such example was a nice 12-18, but was hesitant to dig thinking it was likely trash. Bit since it was a pretty clean park I dug anyway and uncovered a nickel on top of a dime. I have also been sering a lot of zincolns ranging from 12-34 all the way up to 12-45. Has anyone experienced anything like this or is my machine going wacky?
