Harry (Doc) Gessler appears on card #59 of the 1915 Cracker Jack baseball set, a popular tobacco-era issue among vintage collectors. Listed as Unknown rarity, the card nevertheless commands a current market value of $5,880.00, reflecting scarcity and demand for centennial-era pieces. Collectors use grading and sales history to assess condition-sensitive value, as well as set-completing interest within early 20th-century baseball series.
