Isabella Commemorated
Isabella was the first woman to be featured on U.S. postage stamps, namely on three stamps of the Columbian Issue, also in celebration of Columbus. She appears in the 'Columbus soliciting aid of Isabella', 5-cent issue, and on the Spanish court scene replicated on the 15-cent Columbian, and on the $4 issue, in full portrait, side by side with Columbus.
The $4 stamp is the only stamp of that denomination ever issued and one which collectors prize not only for its rarity (only 30,000 were printed) but its beauty, an exquisite carmine with some copies having a crimson hue. Mint specimens of this commemorative have been sold for more than $20,000. Isabella was also the first named woman to appear on a United States coin, an 1893 commemorative quarter, celebrating the 400th anniversary of Columbus's first voyage.
