What Wayne Manor is
Bob Kane and Bill Finger introduced Wayne Manor in Batman #1 (Spring 1940). The Wayne family’s ancestral mansion is Bruce Wayne’s surface-level home; the Batcave beneath the manor was established in Detective Comics #83 (January 1944). The manor has been canonical across nearly every Batman continuity since 1940.
Collector context
Batman #1 is one of the highest-value Golden Age comics; CGC 9.0 and above is in the seven figures. Wayne Manor’s first-appearance value is folded into the broader Batman #1 pricing driven by the Joker first appearance and the foundational Batman significance.
