How to read this

Triumph values this slab at $8,736. That's 17.5× the $500 it costs to open the pack — which is exactly why it's showcased. But a pull landing anywhere in its $900–$10,000 value band carries a 3.8% chance, so this is the ceiling, not the expectation. The slab is graded PSA 10 — the top grade a card can receive.

The grader's certification number (114379715) is legible on the slab label in our source screenshot, so this specific card is independently checkable against PSA's own records.
