Important COMC Auctions Reminders

  • The minimum fee per auction is $3.50, regardless of the final sale price. For a full breakdown of COMC Auction fees, see the COMC Auction Schedule and Fees blog.
  • We strongly recommend you only submit cards to auction that will sell for approximately $50 or more. COMC Auctions reserves the right to change the service level of new Auction submissions to our Select Processing Service Level if submissions primarily consist of items valued less than $10.
  • There are no cancellations once we receive your auction submission. If you want to instead consign your high-end trading cards through COMC as buy-it-now listings or field offers on the marketplace, we encourage you to submit them using our Elite Service. All Elite Items are eligible to be transferred to auction at a later date.
  • Please review our Supported Trading Cards criteria if you have any questions about what items you can consign with COMC.
  • COMC is also proud to announce we are now accepting HGA Hybrid Grading Approach slabs for submissions. HGA gets added to a list of supported grading companies; including PSA, BGS, BVG, CSG, and SGC!
