The two grading companies: labels, holders, certification numbers and how to read a slab.
CGC / CBCS
A CGC cert look up means entering the certification number printed on the slab's label into the grader's online verification tool and comparing the record it returns to the book and label in your hand. A match on title, issue, grade and label details is the check that matters.

The value of CGC graded comics is set by the numeric grade, the page quality noted on the label, the label type (including any restoration), and demand for that specific issue. The only reliable figure is what the same issue in the same grade recently sold for.

A CGC 5.0 is a mid-grade comic: complete and structurally sound, but with clear signs of age and handling such as creasing, wear, small tears or minor staining. The grade carries a price well below high-grade copies of the same issue, and the gap varies by book, so compare recent sold prices for that exact issue at 5.0.

CGC grades run from 0.5 to 10.0 and describe the physical condition of a comic as judged by a third-party grader, who then seals the book in a tamper-evident holder. A higher number means fewer and smaller defects, and because collectors pay for condition, the grade is one of the biggest factors in what a book sells for.

Tales of Suspense #39 (March 1963) is the first appearance of Iron Man, and its price depends mostly on the CGC or CBCS grade, then on page quality, label type and the date of the sale you compare against. No single price applies, so check recent sold prices for the exact grade.

CGC comic grading means a third-party company examines a book, assigns a grade from 0.5 to 10.0 and seals it in a tamper-evident holder. Graders judge physical defects and restoration, and the resulting number is a major driver of what a collector will pay, alongside the book's scarcity and demand.

There is no single CGC graded comics price guide that works for every book. The price of a slabbed comic is set by the issue, its numeric grade, the page quality, the label type, and what the same issue at the same grade has recently sold for.
