Is it worth grading Gyarados XY Black Star Promos XY109/211?
A PSA 10 currently sells for about $8,740, raw the card sits at $64.36 — 135,8× as much. Of 691 copies already graded, 4 % received a 10 and 19 % a 9. Mathematically, submitting returns $1,105 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.

Below which price is an offer for Gyarados XY Black Star Promos XY109/211 unrealistic?

How does lastsold determine the market value?
lastsold 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.
