A PSA 10 2015 BREAKthrough Mewtwo EX #158 is valued at about $5,955, a price-guide estimate rather than a recorded-sales median. Its 99 recorded PSA 10 sales in the last year ranged from $650 to $6,000; they have not yet passed Slabline's checks (a sharp price move, a wide spread, or possibly another printing's sales), so the value shown stays on the price guide until they do.

Value by grade
How much the 2015 BREAKthrough Mewtwo EX #158 is worth at each grade.
How to read this page: an estimate is Slabline's figure for a grade, built from the source named beside it. An observed price is the latest price a grader's copy of this card fetched, one cell per grader and grade in the grid below. A recorded sale is a dated transaction with its venue. The headline above is the estimate for this slab's own grade.
Estimated from this category's observed grade curve and this card's known value, not from this card's own sales at each grade (the recorded sales are above). Estimates, not observed prices.

Frequently asked
How much is a PSA 10 2015 BREAKthrough Mewtwo EX #158 worth?
A PSA 10 2015 BREAKthrough Mewtwo EX #158 is worth approximately $5,955, the price-guide estimate for this grade. Card values fluctuate with the market.
How does Slabline value the Mewtwo EX card?
Slabline starts from the price guides for the card and grade. When it holds dated recorded sales of that exact card and grade — from CardHedge market data and the auction houses it ingests — the headline becomes the median of the most recent ones and the grade ladder rescales to match. Each row on the page names which of those it is.
Values are informational estimates built from recent comparable sales — not a certified appraisal, insurance, or financial advice. Card values fluctuate; figures are a snapshot and may differ from a realized sale.
