What is the value of an 1855 US 20 dollar gold piece?

Answer 1

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

Look on the back of the coin to see if there's a small mint mark letter below the eagle. It may be blank or there may be an O or S.

No mint mark (Philadelphia):

Very worn condition - $1,580

Moderately worn - $2,220

Slightly worn - $2,380

Almost no wear - $4,176

Uncirculated - $9,560 to $55,010 depending on quality

"O" mint mark (New Orleans):

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.
