Against selling raw at $18.83, 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 244 copies; 84 got a 10.

About this card
Unit Energy GrassFireWater is card 170 of 156 in the Ultra Prism price guide, a set released in February 2018 during the Sun & Moon era. Its number runs past the set’s printed 156, which marks it as a secret rare. In the checklist it sits after Peeking Red Card 169/156 and before Unit Energy LightningPsychicMetal 171/156.
It is the 28th most valuable of the 178 priced cards in Ultra Prism, behind Lillie 151/156 (see the most valuable Ultra Prism cards).
What the data says
Only 2 ungraded copies sold in the last 90 days, too few to check the value against.
A PSA 10 is valued at 5.8× the ungraded price ($110 against $18.83), and a PSA 9 at $26.50.
PSA has graded 244 copies, 84 of them PSA 10 (34%). That describes the copies sent in, not the chance a given card grades 10.
