The Modern Age starts with the Image founders in 1992 and continues today. It is the most liquid part of the market: first appearances that are later adapted to film and television move quickly, and variant covers with tiny print ratios can outperform books forty years older.
Modern books are collected almost exclusively in 9.8, so grade is everything. A 9.6 of the same issue often trades at a fraction of the 9.8 price. Every modern slab we list is a recent, unaltered holder with a verified certification number, and we flag newsstand editions and low-ratio variants separately.
Every book ships double-boxed, signature-required and insured to full value, and you have 14 days from delivery to inspect it. Undisclosed restoration is refundable with no time limit under our authenticity guarantee. Have Modern Age books of your own to grade or sell? Start a grading submission or request an appraisal.
