What is the value of a 1922 US 20 dollar gold piece?

Answer 1

Look on the front of the coin to see if there's a small mint mark letter above the date. It may be blank or there may be an S. (The intertwined letters below the date are the designer's monogram and not a mint mark.)

1922 isn't a rare year for St. Gaudens double eagles. In lower grades the coins are valued mostly for their gold content. Numismedia lists the following approximate retail values as of 11/2011:

No mint mark (Philadelphia):

Very worn condition - $1,960

Moderately worn - $1,980

Slightly worn - $1,990

Almost no wear - $2,030

Uncirculated - $2,080 to $21,560 depending on quality

"S" mint mark (San Francisco):

Very worn - $1,960

Moderately worn - $1,980

Slightly worn - $1,990

Almost no wear - $2,236

Uncirculated - $2,410 to $65,630

DISCLAIMER: The retail values quoted are the best available as of the date shown, but may vary significantly due to changes in the precious metals market. Also the wholesale (buying) price of a coin will be less than the selling (retail) price. A reputable coin dealer will be able to give a more accurate valuation based on inspection of the coin.
