The market price

The market price is the TCGplayer price for the printing you picked.

Where the market number comes from

A card game card is priced from the TCGplayer market price for the printing you picked.

We hold that table ourselves and update it every day, so the number is there the moment the card is read.

The number is for one printing. A Reverse Holo and a Non-Holo are two rows with two prices, so the number changes the moment you pick the finish.

Type over it if you know better. The row then reads Your market price.

Sports cards and graded cards are priced from eBay instead.

The condition-adjusted price is the market price after your condition and your finish. The row appears only when the two differ.

Market prices are Near Mint prices. A Lightly Played card is worth less, and this is the row where that happens.
