Official Overstreet Comic Book Price Guide

The Official Overstreet Comic Book Price Guide was first published in 1970 by Robert M. Overstreet. Conceived as a response to the growing need for a standardized reference for the burgeoning comic book collecting hobby, the guide emerged during a time when comic collecting was transitioning from a niche pastime into a serious pursuit. Overstreet sought to provide a systematic methodology for grading and pricing, essentially creating the market framework that allowed the industry to mature into a legitimate field for investment and preservation.

The design of the guide focuses on utility and comprehensive data, featuring dense lists of titles, issues, and market values adjusted for condition. Over the decades, the publication has evolved from a humble mimeographed effort into a massive, heavily indexed annual volume. It is widely regarded as the 'bible' of the hobby, with its standardized 10-point grading scale serving as the international benchmark for comic book collectors, dealers, and auction houses globally.
