Few comics have as interesting or complicated a back story as Cage’s copy of Action Comics no. 1. Certified Guaranty Company, the leading grader of the quality of collectible comics, recently assigned this copy a grade of 9.0, making it the best-preserved publicly-known copy of Superman’s first appearance. Approximately 100 copies of Action Comics no. 1 remain in existence. Experts believe only about five others, all in private hands, are of comparable quality to this copy. Sotheby’s sold this comic at auction in 1992 for a then-record $82,500. Cage bought it in 1997 for about $150,000. - DemocraticUnderground.com
