Another coin designed by Chief Engraver James B. Longacre, was the $3 gold piece. The mint issued these coins from 1854 to 1889. A beautiful obverse featured Liberty as an Indian princess, and is still referred to as the gold “Princess” coin. This unusual denomination was attributed to being able to purchase the postage stamp in quantities because postage was now three cents. Also, this was mentioned as a reason for the production of the three cent nickel and silver coins. A $3 “Princess” coin would be a great addition to your gold type coin set.
