The ground has finally thawed in Central PA! I decided to hunt an old property I recovered 3 Large Cents from last November. I was using the stock coil on my E-trac. This time I decided to run the SEF 12x10. The first day I scored 7 colonial coppers and 2 Draped Bust Half Cent! The second day netted 3 more coppers, another Draped Bust Half Cent and a Classic Head Half Cent! Firsts all the way around!!!! The copper are 5 George IIIs from 1773 - 1775, 3 Auctori Connec. 1787 Coppers and 2 Unknowns!!! I had hunted the same spot with stock coil! I couldn't believe there was so much left. I can't say enough good about the SEF coils! Thank you!!!
