I believe that George III is often depicted with long hair. Also, the Indian on the USA nickel has his long hair in a braid. Note that the two USA nickels depicted are fakes.
Trivia about Columbus images I understand that there are no contemporary images of Christopher Columbus. All likenesses are from written descriptions of the man. He may have had long or short hair. He may also have been heavy or thin, bearded or clean shaven.
from wikipedia (everybody's favorite source...) The coin stems from the desire of the Columbian Exposition's organizers to gain federal money to complete construction of the fair. Congress granted an appropriation, and allowed it to be in the form of commemorative half dollars, which legislators and organizers believed could be sold at a premium. Fair official James Ellsworth wanted the new coin to be based on a 16th century painting he owned byLorenzo Lotto, reputedly of Columbus, and pushed for this through the design process. When initial sketches by Mint Chief Engraver Charles E. Barber proved unsatisfactory, fair organizers turned to a design by artist Olin Levi Warner, which after modification by Barber and by his assistant, George T. Morgan, was struck by the Mint. I understand Barber is responsible for the obverse, Morgan responsible for the reverse.
