Starting a sports card business means buying, grading, and reselling cards to collectors and investors, both online and at local shows. Demand is steady across vintage, modern, and graded singles.
The category is growing. The sports trading card market is projected to grow by USD 5.72 billion between 2025 and 2030, at a 9.4% CAGR, according to Technavio.
This guide covers validating your niche, sourcing inventory, licensing, pricing, and marketing. It also shows how to accept card payments at shows with Tap to Pay at 1.99% per sale, so you get paid the second a buyer says yes.
What do you need to start a sports card business?
You need $2,500 to $11,000: inventory, shipping supplies, basic equipment, and business formation. Inventory is the biggest line.
Before buying, validate your niche. Track recent sold listings on eBay to see what buyers actually pay, not what sellers ask, and pick a focus such as a sport, era, or player.
Here is a realistic startup budget:
| Item | Estimated cost |
|---|---|
| Initial inventory | $2,000 to $10,000 |
| Shipping and card supplies | $300 to $500 |
| Equipment (scanner, thermal printer, lightbox) | $300 to $600 |
| LLC formation | $100 to $800 |
| Selling and platform fees | ~$30 to $100 per month |
| Total to launch | $2,500 to $11,000 |
Keep cash in reserve. A common mistake is putting every dollar into cards, leaving nothing to ship orders or grab a collection that pops up.
If you need capital, the SBA Microloan program offers loans up to $50,000, averaging around $13,000, at rates between 8% and 13%.
How do you set up the business legally?
Form an LLC, get a state seller's permit, and secure a local business license. No federal license is required to sell cards.
An LLC separates your personal assets from business debts and offers pass-through taxation. A sole proprietorship is simpler but gives no liability protection.
Your legal checklist:
State seller's permit
From your Department of Revenue, so you can collect sales tax. Usually free.
Local business license
From your city or county clerk, typically $50 to $150 a year.
EIN
A free federal tax ID you get instantly from the IRS, required if you form an LLC or hire.
Apply for the seller's permit early. Selling without one is a frequent oversight that creates tax problems later.
Where do you get inventory and equipment?
Source inventory from three channels: individual collections, online marketplaces, and wholesale distributors. Each has a different margin profile.
To buy new sealed product at wholesale, you need accounts with hobby distributors. Most require a registered business and, often, a storefront before approving an account.
Your core equipment:
Scanner or photo lightbox ($30 to $200+), because clear images sell cards faster.
Thermal label printer ($200 to $250), which saves on ink over time.
Digital shipping scale ($20 to $40) for accurate postage.
Acid-free storage boxes and shelving ($100+) to protect inventory.
Most sellers start from home. A 100-square-foot space is enough for inventory and shipping, though you should check local ordinances on home-based businesses.
How do you protect your card inventory?
Use Inland Marine insurance, which covers your cards at home, in transit, and at shows. A standard homeowner's or renter's policy does not cover business inventory.
For a $50,000 collection, Inland Marine premiums run $300 to $600 a year. If you sell at card shows, add General Liability insurance, around $400 to $700 a year for $1 million in coverage.
Manage risk beyond insurance:
Photograph and log high-value cards in a spreadsheet.
Always ship with tracking and buy shipping insurance for items over $100.
Store valuable inventory in a safe.
Providers that specialize in collectibles understand this category better than a general homeowner's policy.
How do you price sports cards?
Price singles with comps, the recent sold prices for the exact card. Use eBay's sold listings or a tool like 130point to pull real sales data, not asking prices.
For sealed wax and boxes, use a cost-plus model. A 20% to 30% markup is a typical starting point.
| Product type | Pricing method |
|---|---|
| Raw single cards | Comps from recent sold listings |
| Graded singles | Comps plus a condition premium |
| Sealed wax and boxes | Cost-plus (20% to 30% markup) |
| Bulk lots | Cost-plus |
Always price the all-in cost to the buyer. A $5 card with $5 shipping is a $10 card, so compare competitors' total price, not just the item cost.
Factor platform fees into every price. A 15% marketplace fee on a $100 sale takes $15 off your revenue before you count shipping.
How do you find customers and sell your cards?
Sell where collectors already gather: online marketplaces, social media, hobby forums, and in-person card shows.
Instagram is built for showcasing cards. Post clear scans, use hashtags like #thehobby and #sportscards, and stay consistent. Hobby forums build credibility faster when you answer questions before promoting your store.
Card shows put you in front of active buyers. A table at a local show costs $50 to $150. When you sell there, Tap to Pay lets a buyer tap a card, Apple Pay, Google Pay, or Samsung Pay on your phone, and the sale settles to your JIM Card in seconds.
For remote buyers who message you on social, you can send a Payment Link they pay online at 4.99% + $0.30 per sale, no app download on their end.
How do you get paid?
Match the payment method to the channel. Online marketplaces handle checkout for you; in-person and direct sales are where you choose the tool.
At shows and meetups, Tap to Pay charges 1.99% per sale, with no monthly fee and no hidden costs. Your phone becomes the card reader, so there is no extra hardware and no waiting on a bank transfer.
Instant funds matter in this hobby. When a great collection appears at a show, the money from your last sale is already on your JIM Card, ready to reinvest. On a $50 sale, the 1.99% fee is about $0.99.
The JIM Card is issued by Lead Bank, Member FDIC, pursuant to license from Visa U.S.A. Inc. Instant settlements subject to terms. Fees and T\&C apply. See jim.com for more details.
Keep your grading consistent to protect your reputation, using a clear standard based on PSA guidelines, and track your return rate below 2%. When you consistently spend more than 15 hours a week on packing and listing, it is time to hire part-time help.
Turn your phone into a card reader and start accepting payments with Tap to Pay. You are ready before your first buyer reaches the table.
