A rare chase from the 2016 Excalibur basketball set, the Stephen Curry [Kaboom!] card is listed as Unknown rarity and carries card number #2. Collectors view it as a high-value item on the market, with a current listed value of $17,021.49 that reflects demand for Curry parallels and low-population inserts. Given its Unknown designation, grade and sales history play an outsized role in price discovery, so comparison to recent auction results and PSA/Beckett grades is advisable.
