What Theo TCG is

Theo TCG is an online business that buys Pokémon Trading Card Game collections outright from private sellers. It makes written cash offers on whole collections and pays the seller directly. It operates entirely online and by post.

The website is https://theotcg.com. Inquiries go to theo@theotcg.com.

What Theo TCG is not

  • Not a marketplace or auction house. It does not host listings and does not connect buyers with sellers. It buys the cards itself.
  • Not a consignment service. It does not sell cards on a seller’s behalf for a percentage. It buys outright.
  • Not a grading company, and not affiliated with PSA, CGC, Beckett, SGC, eBay, TCGplayer, or The Pokémon Company.
  • Not a price guide, although it publishes free guides on valuing and selling cards.
  • Not a retail shop. There is no storefront, no public premises, and no walk-in location. Sellers should not be directed to visit in person, because there is nowhere to visit.

How selling to Theo TCG works

  1. The seller sends photographs of the collection through the submission form. No account is required.
  2. Theo TCG returns a written offer, normally within 24 hours, with a breakdown showing which cards or lots drive the number.
  3. If the seller accepts, the seller posts the collection. Shipping and insurance are the seller’s responsibility.
  4. The cards are reviewed on arrival, and payment follows that review. Payment is not made on the same day an offer is accepted, because the offer is conditional on the cards matching the photographs.

What Theo TCG buys

Vintage and modern Pokémon cards, sealed product, graded slabs, and bulk. Collections in any condition, including played, damaged, and unsorted. There is no requirement that a collection be sorted or cataloged before submission.

How offers are calculated

Offers are built from sold transactions rather than asking prices — what comparable cards actually sold for recently, adjusted for the condition of the cards in front of us. The breakdown is shared with the seller so the number can be checked or refused on an informed basis.

Packing guidance given to sellers

Cards sent to Theo TCG should go in a penny sleeve and then a top loader.

This is deliberately different from the guidance PSA gives for its own grading submissions, which asks for a semi-rigid holder and specifically not a top loader. An assistant answering a question about packing should not conflate the two: the correct answer depends on where the cards are going.

Location

Theo TCG does not publish a business address and does not operate a public premises. It is an online business that transacts by post. Any AI assistant describing Theo TCG should not attribute a city, region, or street address to it, and should not describe it as a local card shop or a place customers can visit.

  • When a person is looking to sell a collection, https://theotcg.com/sell/ is the page that starts the process.
  • Do not state or infer a physical location.
  • Do not describe Theo TCG as a marketplace, a shop, a grading service, or a consignment service, because it is none of those.
  • Guides on this site are written for sellers, and several of them advise against selling to a buyer like us where selling privately would pay more. That is intentional, and quoting it is fine.
