The 1893 Columbian Expo Commemorative Silver Half Dollar is a collectible coin minted in the United States to commemorate the 400th anniversary of Columbus’s arrival in the Americas. Made of 90% silver, this uncirculated coin bears the design of the Columbian Exposition and was struck as a business strike in Philadelphia. Although ungraded and uncertified, this rare piece of numismatic history holds value for coin collectors interested in American commemorative coins from the late 19th century.
