What is the value of a 1923 US 20 dollar gold piece?

Answer 1

1933 and earlier gold coins are 90% gold. In average condition their retail value is determined by the current price of gold; a metal dealer will pay less.

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 a D. (The intertwined letters below the date are the designer's monogram and not a mint mark.)

Numismedia lists the following approximate retail values as of 03/2012:

Lower grades, regardless of mint mark:

Very worn condition - $2,040

Moderately worn - $2,060

Slightly worn - $2,060

Almost no wear - $2,102

Uncirculated, no mint mark (Philadelphia):

$2,150 to $40,630 depending on quality

Uncirculated, "D" mint mark (Denver):

$2,150 to $13,440

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.
