No old silver. These were modern (at that time) WW2 era to date - and I think it was about '62 or '63. A high surf had cut the beach and left about a ten foot cut. The coins were near the surface below the cut. If this happened today you wouldn't be able to find a parking place near the beach because of all the detectorists already out there. But there were only a few into the hobby then.....I have seen similar beach erosion leave a lot of coins and jewelry since, but never like that.
It's amazing how the surf will move coins around - and SORT THEM OUT. I guess because of similar size/weight, the same domination of coins tend to accumulate together after a surf event like that. At one distance from the water's edge you'll find pennies, at another distance quarters, etc, etc. My hunting buddy and I found a little over $100 together in quarters and dimes one day after a winter storm racked the beach. The quarters were in a strip of beach about 20 feet wide by 60 feet long...and there was literally nothing anywhere else along the beach. I'm waiting for that day when all the diamond rings are clumped together. lol
