Each graded row counts only that grade's sales; the ungraded row counts every condition. Sales a month is the 90-day pace. Last sale is the latest verified sale, never an asking price. How we calculate the UltraBall Market Value

Against selling raw at $0.40, after the PSA fee for what the slab is worth (a 10 goes in at Standard, $59.99; a 9 at the same level), $25.00 shipping and insurance, and eBay US selling fees, as the selling calculator works them out, with its usual $5 postage and $1 packing on each sale: the same sum as the selling calculator. Each grade is charged the fee level its own slab price needs, so the break-even price carries the fee for a slab at that price, not the PSA 10 fee. These are outcomes if the card gets each grade, not the chance that it will. PSA has graded 70 copies; 43 got a 10.
