So-Called Dollars are a category of collectible coins that often commemorate events, places, or notable individuals, primarily issued as souvenirs or medals rather than official currency. The term is named after the author of "So-Called Dollars," Hibler and Kappen, who compiled a comprehensive reference work on these pieces. The coins can include various designs and materials, and one notable piece is a So-Called Dollar from 1825, which reflects the historical context and sentiments of its time, often sought after by collectors for its rarity and significance in American numismatics.
