What is the value of an 1899 US 10 dollar gold piece?

Answer 1

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.

Numismedia lists the following approximate retail values as of 02/2011:

No mint mark (Philadelphia):

Very worn condition - $770

Moderately worn - $800

Slightly worn - $820

Almost no wear - $848

Uncirculated - $930 to $43,880 depending on quality

"O" mint mark (New Orleans):

Very worn - $770

Moderately worn - $800

Slightly worn - $820

Almost no wear - $876

Uncirculated - $1,020 to $35,630

"S" mint mark (San Francisco):

Very worn - $770

Moderately worn - $800

Slightly worn - $820

Almost no wear - $848

Uncirculated - $930 to $31,730

Of course a scrap dealer would pay wholesale prices, and IMO the idea of melting these coins is ill-advised because it is destroying a historical item for short term profit.

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.
