Howdy Mark--
Congratulations on those finds! That's good advice to detect near streams, rivers etc. I learned that in the early 1980's. I was captain of a team in an Eight Ball pool league in western NY (We took 1st place in 2 consecutive years). After a match, the boys would indulge in adult beverages and play a few games. It was not unusual for $$$ to change hands. One of our opponents worked at the Chevy Plant near the Niagara River and on his lunch break, he would go down to the river and detect with his Fisher 1260X. He showed me baggies full of Barber Dimes, Barber Quarters, and Barber Halves that he had dug there. With my love of numismatics, I incorporated coin shooting in my detecting strategy (formerly exclusivly a cache hunter). Now, living in west Texas, I have hunted an old Texas Trail, along the Pecos River and have dug my share of military relics and coins. Unfortunately, due to health reasons, my detecting days are nearly over. Keep digging those goodies! I can experience the thrill and excitement of your finds. Best of luck and...
Happy Hunting!
