On a phone, Scan an item opens your camera. Photograph the barcode, or the item itself if it has none (cards, coins, comics), then add more angles: back, label or maker's mark, signature, and any damage. Gemini identifies the item from your cover photo and searches recent sold listings for a live price (Gemini Live Comps); photos you identify are sent to Google. Pokémon, Magic and Yu-Gi-Oh! cards are priced from free card databases. You can always open an item, use Fetch comps, and paste the eBay or PriceCharting page. Sold prices for the same grade and variant always set the value; if nothing has sold, asking prices from active listings are used instead (marked ask), and anything else shows as a dashed est. sticker.
