There is no 1921 barber silver dollar, it is either a peace dollar (eagle perched on a rock engraved PEACE on the reverse) or a Morgan dollar (Eagle with gothic lettering above it saying "In God we Trust" on the reverse)
The first Peace dollars were struck in 1921.
The Morgan silver dollar was not produced in the United States after 1921, and the Peace Dollar was only produced until 1935. In fact, I don't believe that there were any coins produced in the world in 1939 with the denomination of One Dollar.
All Morgan and Peace $1 coins were struck in an alloy of 90% silver and 10% copper. The coins' nominal weight when new was 26.7 gm so that means they contain about 24 gm of pure silver.
