What is the value of an 1887 US 10 dollar gold piece?

Answer 1

1887 is a fairly rare year for gold eagles so any coin with that date needs to be authenticated in person by an expert. Look on the back of the coin to see if there's a small mint mark letter. It may be blank or there may be a CC or S.

Numismedia lists the following approximate retail values as of 05/2011:

No mint mark (Philadelphia):

Slightly worn - $2,600

Almost no wear - $10,282

"CC" mint mark (Carson City):

Moderately worn - $4,140

Slightly worn - $5,160

Almost no wear - $18,738

"S" mint mark (San Francisco):

Moderately worn - $930

Slightly worn - $960

Almost no wear - $4,252

Uncirculated - $25,000

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.
