Is it worth grading Blastoise GX SM Black Star Promos SM189/248?
A PSA 10 currently sells for about £663.48, raw the card sits at £14.86 — 44.6× as much. Of 2.158 copies already graded, 25 % received a 10 and 50 % a 9. Mathematically, submitting returns £213.67 on average, before fees and shipping. Rule of thumb: submit when the value at a realistic grade is at least double the raw value — which is the case here. Centering decides it: an off-centre card will not get a 10. The grade distribution comes from the PSA Population Report; people pre-sort before submitting, so your own hit rate may differ.
Auction or Buy It Now — which gets more for Blastoise GX SM Black Star Promos SM189/248?

Half of all sales fell between £9.21 and £14.44, with a median of £11.71. Selling fast lands you nearer the lower end; with patience, good photos and a complete title the upper end is achievable.
Below which price is an offer for Blastoise GX SM Black Star Promos SM189/248 unrealistic?

How does Last Sold determine the market value?
Last Sold uses only real sales — eBay plus auction houses like Goldin & Fanatics — recent sales count more (recency weighting), outliers and fakes are removed. It's not an estimate but actual sold prices, separated by condition, language and grading.
