Grading
A grading read appears once Onix has a PSA population census. Riffle captures the census monthly; this card doesn’t have enough graded copies on record yet.
- under $1 is the middle 80% of clean market activity, not the cheapest listing and not the most hopeful one.
- The band spans about ±33% around its midpoint: a wide spread, so read it as a range, not a point.
- Sampled daily since July 28, 2026, current as of September 12, 2026.
When the data thins, the band widens and says so, it never fakes precision. Exact source prices are part of Riffle premium; the band is Riffle’s own figure to publish. How these numbers work →
