Sell My Comic Books is a comic book buying and appraisal service that helps people identify, value, and sell vintage and other collectible comics. It assists sellers with inherited collections, books found at home, or comics they have acquired, aiming to help them achieve a strong return. Visitors can request a free appraisal, use extensive online price guides, or consult educational articles to research comic values, grading, and the selling process.

For collections suitable for auction, the company offers consignment through Goldin. Its step-by-step service includes reviewing a comic list, requesting photos when needed, providing an appraisal, arranging a digital contract, and guiding sellers through secure shipping. After a sale, payment is made by check or ACH, with wire transfers available for overseas clients. The site states there is no seller fee for Goldin auctions, as the buyer pays the fee, and provides typical payment timelines depending on whether comics are already graded.
