1921 3 Coin P, D, S Morgan Silver Dollar Set $1. Designed by George T. Morgan, Morgan silver dollars were struck from 1878 to 1904, and then one last time in 1921. All three of the historic 90% silver Morgan dollars offered here were minted in that final year of production. This set includes the 1921 Philadelphia Mint issue, 1921 San Francisco Mint issue, and the only Denver Mint Morgan dollar issue, as this mint opened for business in 1906.Please Note All Backer Cards may have slight differences but will be very similar if not identical to the one in the photo
