Frequently asked questions

Is it worth grading Bronzong SWSH Black Star Promos SWSH091/307?

A PSA 10 currently sells for about £92.34, raw the card sits at £6.91 — 13.4× as much. Mathematically, submitting returns £92.34 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.

Is the English or the German Bronzong SWSH Black Star Promos SWSH091/307 worth more?

From real sales: Italian £3.62 (11), English £2.99 (26). Italian fetches about 21 % more.

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.
