U.S. Mint 25c size collar die, doubtless intended for a Washington 25c. The collar has a reeded edge inside, and is only partially defaced (melted.)
A collar die, the "3rd die", is used to strike or being impressed against a coin's edge. It's purpose primarily is to retain the metal flow when a coin is struck, and also to impart a plain, reeded or other type of edge to the coin's edge.
Collar dies are much scarcer than obverse or reverse dies that are seen on the market, and although probably 100 or so (very rough estimate) are known, they are not often found for sale. This die was doubtless from the 1960's, which is when most are believed to have come onto the market.
