It was'nt more than 3 in., I found it on the shore of a remote lake seldom visited. I have since discovered that there were, many yrs. ago a few cabins around that the state tore down when they bought the land. And a logging and tourist train was located on this spot until the 1920's. In the same 10 by 10 ft. area I picked up quite a few pennies but the thiness of this object has me puzzled, and yet it the same width as a penny,maybe the damn thing got struck by lightning or some thing?? I've had it in olive oil for about 4 weeks and theres no sign of flaking or debris yet. If it's any thing interesting will post it. Also within a within 3 mi. of this spot was a home, post office,railstop,dance hall and boat pier where they picked up fisherman. I'm hot to trot for this spot but I'll have to wait until a very nasty day ( 30's with rain and lots of wind) as it's the only boat landing on this lake and I dont want to have anyone nosing around when I'm scanning.
