 Mom fined $88,000 after kids collect 72 clams from California Beach thinking they were seashells. Charlotte Russ. I knew the price of clams was going up, but I didn't realize it had gone up quite that much. It's even more expensive than going to Popeye's on the New York Thruway. The fine said market value. MP, no, market price, right? Isn't it MP? Whatever it is.
