Pop Report
Also known as: population report, pop
A pop report (short for "population report") is a publicly accessible database maintained by grading companies like PSA and BGS that shows the total number of copies of a specific card that have been graded, broken down by grade level. Collectors and investors use pop reports to gauge rarity — a card with a PSA 10 pop of 5 is far rarer (and usually more valuable) than one with a PSA 10 pop of 500. Low-pop cards with high grades are often referred to as "low pop" or "registry worthy."
