Chesapecten, one of our more common fossils. They range from dime size to nearly plate sized.
Mya arenaria. A common clam up and down the East Coast, they are sought after for food as soft clams, manos, piss clams, steamers, etc. etc. There is an active fishery for them in the Chesapeake, using a destructive dredge boat, but I've never seen clam dredgers near here, only in the Patuxent River.
Turritella shell. Definitely a fossil, these are fragile, and moderately rare here, but common enough elsewhere as to be valueless. Given the large numbers of Turritella species, I wouldn't even begin to guess which one.
nacreous layer (mother of pearl, the stuff that make pearls shine).
