Frequently asked questions
Is it worth grading Colress's Experiment Crown Zenith GG59/159?
A PSA 10 currently sells for about £41.12, raw the card sits at £3.29 — 12,5× as much. Of 1.175 copies already graded, 58 % received a 10 and 31 % a 9. Mathematically, submitting returns £31.87 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 Colress's Experiment Crown Zenith GG59/159?
Across 14 auctions the median was £2.89, across 157 fixed-price sales £3.48. Fixed price therefore fetched about 20 % more — for this card patience with a set price is the better route.
What will I get for Colress's Experiment Crown Zenith GG59/159 if I want to sell quickly?
Half of all sales fell between £2.80 and £4.19, with a median of £3.27. 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 Colress's Experiment Crown Zenith GG59/159 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.
