Well now you seen how fast it can happen and if you make a strong effort it will get better and better. I have quite a few early silver coins now so people probably assume it's fairly easy digging them here, and I have been finding them all along, but that's not the case. I think I had about a year and a half in and my only old silver coin was a George III sixpence that was off the shore and very gray. As time went on we really put the time in to find old sites and eventually the silver coins started to come. I went from one in 1.5 years to finding 2 (British, Spanish or French) on the same day many different times. Last year however it seems my luck has changed for the worse and I was back wondering where all the old silver is. (but it doesn't matter because I have already found my share plus some)
PS: Your best finds will be ones you never expected you'd find, or maybe never even thought about. One day it just happens.
