Collectible coins, also known as numismatic coins, encompass a wide range of items, including commemorative pieces, historical currency, and limited-edition releases. The 1909 Hudson-Fulton Celebration coin is a notable example, minted to commemorate the 300th anniversary of Henry Hudson's exploration of the Hudson River and the 100th anniversary of Robert Fulton's introduction of steam navigation. These coins are often sought after by collectors for their historical significance, artistic design, and potential for appreciation in value. Events like world fairs and expositions have historically led to the issuance of special coins to mark the occasion and celebrate achievements in technology and culture.
