Really nice find and a tough one to find at that. It takes a lot of patience to look through the coins besides rim checking. I have advocated that us hunters have a unique opportunity in the volume of coins that we look at that we do ourselves a disservice by not looking for coins that are not silver. Sure, the process takes longer, but based on the decreasing silver finds, it would be worthwhile to take that extra time and look for coins that carry a value greater than the silver they are searching for. Now, it doesn't mean you have to look at every single coin under magnification. But you can identify varieties that carry the higher premium to collectors and focus your efforts.
