Went down to the local beaches tot lot and woo hoo found 29.50 in clad for 45 min hunt. fun stuff The pics are for 1/2 hr, went back found another 4.75.
With that kind of clad in such a short amount of time I would guess there was some sort of coin hunt for kids there not too long ago. Also the fact that you found a few halves which are rare for anyone to be carrying now a days. I've seen it done before where they will throw the clad into the sand then the kids will use their hands to try to find the coins.
No pennys, And yes there was a coin hunt for the kids on sat, the 13th. This was the second year they had it , last year i netted 31.50. Its a fun time with the ace 250.
