How much is an 1841 gold dollar worth?

The US only issued gold $1 coins from 1849 to 1889.

If your coin is slightly larger than a quarter and has a picture of President William Henry Harrison on the front:

(A) It's made of brass, not gold

(B) 1841 is the date he served as president, not the year the coin was struck

(C) The date and mint mark are on the coin's edge

(D) It's a common coin in the Presidential Dollar series and is only worth $1.
