The short answer: start on TCGplayer for raw singles and eBay for everything else, price from live market data instead of gut feel, and only open your own storefront once repeat buyers exist. I have sold Pokemon cards for over six years, on TCGplayer, eBay, Shopify, and Amazon, starting with a store I ran at 14 where I sold wholesale product at break-even and learned e-commerce the hard way. This guide is the system that came out of that.
Where to sell: the honest comparison
| Platform | Best for | Why | Watch out for |
|---|---|---|---|
| TCGplayer | Raw singles | Fastest listing flow in the hobby: search the card, set condition and price, done. Buyers are already searching there. | Commodity pricing pressure; the lowest price wins the sale |
| eBay | Graded slabs, sealed, lots | Biggest buyer pool for anything unique; auctions find the price when you do not know it | Returns and claims need real customer service |
| Shopify (your store) | Sealed, repeat buyers, local pickup | You keep the margin, the email list, and the customer | You bring all the traffic yourself |
| Amazon | Sealed at scale | Massive reach for sealed product | Strictest platform; not where I would start |
Fee reality: plan on roughly 10-15% of each sale going to the platform, before shipping and supplies. Run the numbers in a spreadsheet before you list, not after the fees hit. Exact rates change; check the platform's current fee schedule when you set your pricing rules.
Price from data, not hope
The single biggest beginner mistake is pricing from what a card sold for once, months ago, or what a seller is asking. Buyers pay market price. Look the card up on the live market boards or its card page here, price at or slightly under current market, and the card moves in days instead of months. For chase cards, check the most valuable cards list to see where yours actually ranks before you assume it is a hit. Prices move daily in this hobby; reprice your inventory on a schedule or watch it stop selling.
The skills that actually matter
- Spreadsheets. Excel or Google Sheets is the tool for pricing collections, modeling fees, and tracking what you bought and sold. Every serious question I get from other sellers ends up being a spreadsheet question.
- Basic accounting. You do not need to be a bookkeeper, but you need to know your cost of goods, your real margin after fees, and what records the tax season will demand. A local CPA is worth the call once money is real.
- Customer service. Returns and complaints happen even when you do everything right. Knowing when to refund fast and when to escalate to platform support is a skill, and it protects the seller metrics that keep your account healthy.
- Operational efficiency. Set up your workspace so an order flows one direction: pick, package, label, out. Sorting and shipping are where hours disappear; the sellers who last are the ones who systematized them. My full systems are in the sorting guide and the shipping guide.
The margin reality check
I will be straight with you: margins in this business have compressed for years while the time required has grown. Selling cards can absolutely pay for your collecting habit and teach you real business skills while you are surrounded by a hobby you love. What it will not do is replace a salary in month one. The sellers who make it treat this as an operations game played over years, and they win on efficiency, data, and customer trust rather than on finding one big card.
When to open your own store
Marketplaces bring buyers but keep the relationship. Once people are buying from you twice, that relationship is worth owning: your own storefront keeps the margin, builds the email list, and turns drops and preorders into events. The full setup path, including the platform choice and launch checklist, is in our guide to opening a card store. And before you buy any sealed product to sell, check what it is really worth against pull value on the booster box EV tracker.
