1915

Philadelphia delivered 20,986,220 Buffalo nickels in 1915, a full-capacity production year for the Mint's nickel operations. No design changes, no major varieties beyond the standard Type 2 reverse, and no production disruptions marked the year. The 1915 Philadelphia coin is common in all grades and readily available in Mint State through major dealer inventories.

Strike characteristics for 1915 vary by die state but are generally strong, and Gem-quality examples exist in adequate numbers for specialist demand. Collectors seeking a typical Buffalo nickel type coin from the series' early years often select a 1915 Philadelphia as an affordable representative with good strike quality.

The RMS Lusitania was sunk by a German U-boat off the Irish coast on May 7, 1915, killing 1,198 passengers and crew including 128 Americans. The attack dramatically shifted public opinion in the United States toward possible intervention in World War I, though President Wilson maintained neutrality for nearly two more years. The Panama-Pacific International Exposition opened in San Francisco that same year, celebrating the Panama Canal's completion and marking the city's recovery from the 1906 earthquake. Nickels struck at Philadelphia in 1915 circulated through a country that was growing increasingly uneasy about the European war and its implications for American interests.
