What dealers will pay
Dealers operate on a margin model. They will pay roughly 50% to 70% of TCGPlayer market for raw singles and 60% to 80% for graded slabs of high-demand cards. Vintage chase cards (Base Set Charizard, Neo chase holos) sometimes hit 85% to 95% because the dealer can sell them fast. Modern bulk hits 40% to 50% because the dealer is taking inventory risk on slow-moving cards.
The cleaner the card, the higher the percentage. Dealers do not want to spend time inspecting condition or negotiating sub-tier grades. A binder of organized, sleeved, photographed cards gets faster offers than a stack of loose cards.
How to prepare
Sort your selling material into three tiers. Tier 1: graded slabs and high-value raw singles. Tier 2: medium-value raw singles ($20 to $200). Tier 3: bulk lots and sub-$20 cards. Present Tier 1 in a binder or display case. Present Tier 2 in a binder. Present Tier 3 in stacks or 5000-count boxes for "make me an offer on the whole stack" pricing.
Print a comp sheet for your top 10 cards: recent eBay sold comp, TCGPlayer market, and your asking price. Dealers respect sellers who have done the homework. They will quote closer to retail if you can hold the line on pricing.
Pricing strategy at the show
Set asking prices 15% to 20% above your floor. Dealers will counter; you have negotiating room. Be willing to bundle: a dealer who is taking five of your top cards will pay closer to retail if you throw in some bulk for cost. Bundling is the fastest path to a single-deal sale of a whole tier.
Theft prevention
Card show theft is real and well-documented. Most theft happens during chaotic browsing periods when you are showing a card to one buyer and another buyer slips a slab off your table. Practical defenses: keep your top cards in a locked display case or a binder under your hand at all times. Bring a friend. Photograph your selling inventory before the show; if anything is missing at the end, you have documentation.
The other risk is fake bills for cash transactions. Bring a counterfeit-detection pen. For sales above $500, request electronic payment (Venmo, Zelle, Cash App) and confirm receipt before handing over the cards.
When to walk
If a dealer offer is more than 30% below your floor on a high-value card, walk. There will be another dealer at the next booth. Card shows have 20 to 100 dealers; do not accept the first bad offer because the room feels intimidating. Most shows have a "second walk" where prices firm up in the last hour as dealers try to close out the day.
Selling vs buying at a show
Going to a show to buy is the opposite math. Dealers want to move inventory; floor prices at hour 6 of a show are typically 20% below retail. If you are walking in with cash and a wish list, you will often pay below TCGPlayer for raw singles, especially on bulk lots of mid-tier cards. The hybrid play (sell your bulk to one dealer, buy your chase singles from another) is the most efficient use of a show day.
