99.5% of the coins I dig up in crop fields are pennies. Mostly King Georges followed by U.S large pennies and only occasionally an IH. Problem is copper coins get pitted real bad and most are barely identifiable/not identifiable. Today I got a solid dime signal at the edge of a corn field, thought I had a nice older dime. It was the 1837 large penny in the top row. One of the two in the bottom row is a King George, I can see the head facing right when held up to the light just right. The other one in the bottom row is not identifable at all. I think farmers lost more coins when horses were used to plow the fields and lost less coins when tractors became popular because I should be finding more Indian Head pennies than large pennies. I find a lot more silver in the woods, its about 50/50 silver/copper coins. Maybe farmers 150 years ago were too poor to have silver and were lucky to have a few pennies in their pockets. Are you having the same experience in crop fields?
