This is a 1879-S Morgan Silver Dollar in a NAOH NGC holder. This coin is a Business strike type with a denomination of $1. It was minted in San Francisco and has a composition of silver. The coin has been attributed by me as a VAM-107, see pics for markers.   It is a valuable addition to any coin collection and a must-have for any collector of Morgan Silver Dollars.
