Umbreon VMAX · Brilliant Stars Trainer Gallery TG23/30

Every figure on this page was recorded by this app while pricing this card for somebody, and each one is printed with the date it was recorded. Sold comps come from PriceCharting sold-price history, which is mostly PSA graded. Nothing here is refetched when you load the page, so a number is exactly as fresh as its date says and never fresher.

A median is the middle of the most recent few recorded sales for that grade, and the count it was taken over is printed beside it so you can weigh it. The Trend Score is a transparent weighted composite from 0 to 100, a labeled heuristic rather than a machine-learning model.

The 3-month projection the score carries is backtested at roughly 16 percent median error. The separate next-sale estimate, which the app shows on a live lookup rather than on this page, is backtested at roughly 2 to 3 percent median absolute error on liquid, densely traded cards. Those are two different measurements of two different things, and neither one says anything about the other.

A set verdict such as "undervalued vs peers" is peer-relative: it compares this card against the other top PSA 10 cards of its own set, never against the market and never as a buy order. For the live value, the full grade ladder and the comps behind them, run the lookup in the app.
