What is the price for a double eagle gold coin?

An American "double eagle" coin is a $20 gold piece. The term "eagle" comes from an older set of denominations for US Coins in addition to dollars and cents: the $10 denomination was called an eagle, and the $100 denomination (proposed but never minted) was to be called a "union".

The main denominations of gold coins were the unusually-denominated $2.50, then $5, $10, and $20; so they were called quarter, half, one, and double eagles.

The lower-denomination eagle coins were issued starting in 1795, but double eagles weren't minted until the middle of the 19th century. One or possibly 2 experimental pieces were made in 1849, and regular production started the next year. Double eagles were made until 1933 when gold coins were withdrawn. Only 10 or so 1933 double eagles are known to exist and they're among the most valuable American coins.
