What Is Mavin?

Mavin exists to answer one question fast: what has this exact card actually sold for, across grade and parallel, recently. Like 130Point and Card Ladder, it's a search index over sold data, not a marketplace — nothing gets bought or sold on Mavin itself. It sits alongside price guides as a research tool a buyer or seller checks before setting a price.

• Aggregated completed sales— results are pulled from eBay and other tracked marketplaces, searchable by player, sport, year, set, and card number, showing sale price, date, and a link back to the original listing.
• Photo-based search— on top of the usual text search, Mavin has leaned on image matching that lets a search start from a photo of the card itself rather than typing out the full player/set/number combination, useful for cards with obscure or hard-to-spell set names.
• Grade and parallel filters— results can be narrowed by grading company and grade so a raw sale doesn't get averaged in with a PSA 10 of the same card.
• Trend view— beyond a flat list of sales, Mavin surfaces a price-over-time view for a given card, the same basic idea as a Card Ladder chart but built on top of a free search tool rather than a paid index product.

Mavin doesn't process a sale, hold inventory, or grade anything — it's a search index over data that already exists elsewhere. Coverage is only as good as what it can pull from the marketplaces it tracks, so a card that sold in a private group break, a direct DM sale, or on a marketplace it doesn't index won't show up. Photo search helps with ambiguous listing titles but isn't infallible on a low-quality photo, a heavily cropped scan, or a card with very similar-looking parallels.

• vs. 130Point — both are free sold-comp search engines built around the same core job. The practical difference for most buyers is search method (photo search vs. text-only) and which marketplaces each tool happens to index most completely; neither replaces the other for every card.
• vs. Card Ladder — Card Ladder is a paid subscription product built around market indexes and portfolio tracking on top of its sold data. Mavin is free and search-first: a trend chart for one card, not a sector-wide index or a portfolio dashboard.
• vs. SportsCardsPro — SportsCardsPro pairs its price guide with an actual fee-free marketplace where a sale can happen. Mavin has no marketplace side at all; it's search only, the same relationship 130Point has to a place like PWCC or Fanatics Collect.
