I got my first Spanish silver today! It's a 1751....beats my oldest silver coin (a Seated dime) by 126 years! Man was I pumped when I dug this. Found it in the woods off an old road. The signal was so strong and shallow I really thought it was going to be a Merc or a Rosie. It was in some dirt that was on top of a rock and was only about 2 inches down. The relics are from my last couple of hunts. Love this hobby!
