When you hear that beep you never know what is really there until you dig. I was hunting one of my favorite spots and got a signal which read 62 on the TID. Now this is usually pull tabs or similar trash but since I had recovered several pieces of jewelry I dug it up. It was about the size of a dime but covered with the green oxidation like copper. When I got it home I started removing the green and started to see some detail. After two weeks of carefully removing the oxidation and searching the internet I discovered it was a Roman Arcadius coin from 401-403 A.D. If I were in Europe I would pleased but not surprised to find a Roman coin. But I'm in Oklahoma! What is a 1600 year old coin doing here? I learned two valuable lessons from this hunt: You can find anything anywhere and dig everything because you never know.
