About this report
This population report shows how many copies of each Steam Siege card PSA has graded, how many earned a perfect 10, and what those grades are worth today. A low gem rate means the card is hard to grade well — which is exactly what drives PSA 10 premiums. Census data updates monthly; values update nightly.
