Defenders #51 is a key Bronze Age issue featuring the first appearance of The Ringer (Anthony Davis) and an early Moon Knight appearance alongside Nick Fury.

Graded CGC 9.8 with White Pages, this is a top-tier investment-grade copy with exceptional condition and long-term collector appeal.

High-grade 9.8 Bronze Age keys are increasingly scarce, and Moon Knight-related issues continue to benefit from sustained media exposure and collector demand.

A standout key issue and one of the strongest books in this grouping.
