What it is

A home-based card business selling singles, graded cards and sealed boxes through online marketplaces, social media and the occasional card show. You buy collections, source product and list cards one by one.

Your first three steps

  1. Pick a niche (for example one sport, vintage, or modern rookies) and study recent sold listings to learn real prices
  2. Set up seller accounts on one or two marketplaces and list your first 30 to 50 cards with clear photos
  3. Buy a few small collections locally or visit a card show to find stock, and keep a simple spreadsheet of cost and sale price
Who pays

Hobby collectors, players of fantasy and betting games, parents buying for kids, and investors looking for graded cards.

How it makes money

You earn the gap between what you pay for cards or collections and what you sell them for, after marketplace fees, shipping and grading costs.

Skills that help
  • Knowing card values and which players and sets are in demand
  • Photographing and describing cards accurately
  • Careful packing and shipping
  • Basic bookkeeping
Watch out for
  • Check whether you need a state seller's permit or sales tax registration (marketplaces may collect some tax for you, but rules vary by state)
  • Fakes, altered cards and trimmed cards: learn to spot them or stick to graded cards at first
  • Card prices can swing fast, so avoid tying up all your cash in one hot product
  • Check HOA or lease rules for storing stock and shipping from home
  • Keep records of income for the IRS and consider insurance for high-value stock
