US Silver Dollars - 1921 - There were four separate coins minted for 1921 -The Morgan Silver Dollar - (Morgans were minted from 1878-1921 with a break between 1904 and 1921) The 1921 S - San Fransisco - D Denver and Philadelphia (no mint mark)

1921 was also the first year of the Peace Dollar 1921-1935 The first year 1921 was struck as High Relief - the 1921 was only minted at Philadelphia @ a little over 1 million coins- fairly low - these coins in ultra mint condition fetch a bundle - there is one variety with a matte finish - 10 minted - sometimes hard to tell- it is valued in excess of 250,000 US.

For the series of Morgan dollars 1921 is the most common highest mintage year. Assuming the coin is circulated and depending on grade a 1921 retails at $16.00-$20.00

Every issue of United States coinage has the word "LIBERTY" on it so you could have anything. A 1921 Double Eagle would be worth $20,000-$235,000. A 1921 Morgan Dollar would be worth $19-$60,000. A 1921 Peace Dollar would be worth around $125-$50,000 depending on condition. A 1921 Half Dollar would be worth from $50-$28,000 depending on mintmark and grade. A 1921 Quarter Dollar would be worth $175-$2100 depending on grade. A 1921 Dime would be worth $65-$3600 depending on mintmark and grade. A 1921 Nickel would be worth $4-$2200 depending on mintmark and grade. A 1921 Cent would be worth $0.20-$220.

I will add links to pictures of each of these coins so you can determine what you have. But basically you have something that is worth anywhere between 20 cents and $235,000!

Sorry no O mint in 1921,it's a D or S. The 1921 date is so common even in mint state the buy value is below $40.00.

Assuming the coin is circulated, the 1921-S Morgan is so common retail values are only $31.00-$40.00.
