Is it worth grading Rhydon Skyridge H27/H32?
A PSA 10 currently sells for about £1,632, raw the card sits at £220.76 — 7,4× as much. Of 767 copies already graded, 30 % received a 10 and 32 % a 9. Mathematically, submitting returns £902.66 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.
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.
