Collectible coins, particularly within the United States, encompass various denominations and series that appeal to numismatists. The 10 cents or dime category features the Roosevelt Dime, which was introduced in 1946 to honor President Franklin D. Roosevelt. The 1964 Roosevelt Dime is notable for being the last year that this coin was struck in 90% silver. Additionally, coins minted in Denver carry a "D" mint mark, indicating their origin and adding to their collectible value among enthusiasts.
