How to Sell Physical Graded Pokemon Cards on Ethereum

In the past, I have sold my graded Pokémon cards on eBay. This was when I realized how terrible traditional online marketplaces are. Not only did I only receive ~$10,000 for ~$13,000 worth of sales after fees, I was told that I won’t receive my money for 90 days because my account is unverified. I have more cards I would like to sell but I refuse to be bent over by PayPal and eBay. Is there a marketplace on ethereum I can use to list my cards to potential buyers? I understand gas fees are high but I do not want my money to be held by PayPal for 90 days after purchase. Thanks in advance for any responses guys.
