Selling Online
Where sports cards actually sell online
Collectors ask us for "the TCGplayer of sports cards." There isn't one: TCGplayer is TCG-only (Pokemon, Magic, Yu-Gi-Oh!) and carries no sports categories at all. The sports side is split across a few platforms with very different fee math. Here's the map, vendor to vendor.
Start with these three
The liquidity king
eBay
Sells: Everything: slabs, raw, sealed, and live breaks via eBay Live.
Seller fees: 13.25% final value fee up to $7,500, then 2.35% above that, plus about $0.30 to $0.40 per order. A current promo cuts the fee in half on single cards over $1,000.
Best for: Every vendor. Nothing else approaches its buyer traffic, and eBay Live is the online version of working your table.
Live shopping
Whatnot
Sells: Breaks, raw, slabs, and sealed through live shows and static listings.
Seller fees: 8% commission plus 2.9% + $0.30 processing. The commission drops to 0% on the portion of a sports single above $1,500.
Best for: Vendors comfortable on camera. Show energy translates directly, and the high-value promo favors big slabs.
Auctions, marketplace & vault (formerly PWCC)
Fanatics Collect
Sells: Graded slabs, sports and TCG, with vault storage.
Seller fees: Auctions carry 0% seller fees (the buyer pays a 20% premium) and Buy Now runs 6% when priced near Card Ladder market value, 15% above it.
Best for: Consigning graded inventory. The 0% auction seller fee and 6% Buy Now undercut eBay for market-priced slabs.
Worth knowing
Peer-to-peer slabs
MySlabs
Sells: Graded slabs, sealed wax, some raw.
Seller fees: Around 1 to 3% depending on category, plus payment processing. Verify current rates on their fee page.
Best for: The fee minimizer, if you already have an audience that follows you there.
Consignment warehouse
COMC
Sells: Raw singles in volume, lower and mid-tier slabs.
Seller fees: Per-card processing on submission, 5% on sales, storage after 90 days, and a 10% fee to cash out.
Best for: Moving volume commons without touching them again. Watch that cash-out fee.
Vault-first exchange
Alt
Sells: Graded slabs, sports-heavy.
Seller fees: 7% fixed-price (down to 4% at higher tiers); auctions carry 0% seller fees with a 20% buyer premium.
Best for: Vaulted high-end inventory you also use for comps.
Commons marketplace
Sportlots
Sells: Low-value raw singles and base in bulk.
Seller fees: Tiered by monthly volume; check their fee page because the ladder is steep at low volume.
Best for: Set builders and dime-box inventory.
Scanner app marketplace
CollX Marketplace
Sells: Raw singles priced by scan.
Seller fees: Low, with cheap tracked shipping and escrow-style protection.
Best for: Clearing scanned bulk between shows.
The vendor math, in one paragraph
List everything on eBay because that's where the buyers are. If you're willing to go live, Whatnot turns your table patter into sales and rewards big slabs with its high-value fee break. Consign your graded pieces to Fanatics Collect auctions when you want 0% seller fees and don't mind the buyer premium setting the market. Keep MySlabs in your pocket as the low-fee direct channel once buyers know your name, and send bulk commons to COMC so they earn while you sleep, minus that 10% cash-out haircut. Fee numbers move; always confirm on the platform's own fee page before you commit inventory.
