What is the value of a 1884 14k gold E Pluribus Unam coin?

Please post a new question with the coin's denomination.

To clear things up:

First, the motto is E Pluribus UNUM, and that appears on almost every US coin because it's the national motto so it really doesn't help to ID a particular coin.

Second, the US never made 14K gold coins. All circulating gold coins issued up till 1933 were made of 90% gold and 10% copper, which works out to about 21.6K (0.90 X 24)
