These are from a 3 hour hunt today at ,you guessed it, the grove. The CTX with the 6 inch coil has made this site open up again. It is slow tedious work but well worth the effort. Both of these dimes had iron in the hole with them. The barber is a 1913 and it had a rusty bottle cap in the hole. The Merc is a 1916 PLAIN and it had two rusty nails in the hole. Some day I'm going to see that D on the 16 Merc. I also got a 1911 and 1954-D wheat along with some clad.
