Sealed Mega Starter Set

Why this card has no market price

The market prices on this site come off TCGplayer, where hundreds of sellers list the same product and the daily average is a real market. Sealed Mega Starter Set is not a TCGplayer product and never was, so no such average exists for it. The ladder above is built from recorded sales instead: what copies actually fetched at each grade, whenever they last changed hands.

Read it that way and it holds up. A market price moves every day, a sale price moves when a copy sells, and at this level that can be years apart. $0£0€0 is what the last gem copy is on record for rather than a quote you can act on this morning, and the next sale will land either side of it.
