Unidentified nickel

[Bejamble]

Found a nickel today that has me stumped. Its a jefferson but is far too light. Looks like it is zinc. Found in the saltwater. It weighs 2.2 grams compared to I think 5 grams what it supposed to weigh. Any ideas.

Just eaten up from being in the surf for years. I find ones like that all the time.
