About this report
This population report shows how many copies of each Holon Research Tower 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. Click any card for its full price history, every grade’s value, and population across all grading companies.
