Monster Comps
In private testing on iPhone · App Store release coming

Scan a card.
See what it's worth.

Point your phone at a trading card or a graded slab. Monster Comps reads it, finds the exact card, and shows what it sells for, with links to buy it.

The Monster Comps icon: hand-drawn graded cards in front of a rising green and a falling red price line, $1280 and $610

How it works

1

Scan

Raw cards and graded slabs. The camera reads the name, number, set and grade from the card or its label.

2

Confirm

When a card comes in several versions, such as a holo, a reverse holo or a promo, you pick yours from the list.

3

Price

A price guide for each grade, recent sales and current listings, and links to the card on the marketplaces.

Cards it knows

  • Pokémon
  • Magic: The Gathering
  • Yu-Gi-Oh!
  • One Piece
  • Sports cards

Where the prices come from

Monster Comps shows public market data from price guides, marketplaces and auction houses. Every price in the app names its source and links back to it.
