Frequently asked questions
Is it worth grading Professor's Research Crown Zenith 150/159?
A PSA 10 currently sells for about €29,75, raw the card sits at €2,60 — 11,4× as much. Of 517 copies already graded, 61 % received a 10 and 30 % a 9. Mathematically, submitting returns €25,15 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 Professor's Research Crown Zenith 150/159?
Across 15 auctions the median was €2,35, across 111 fixed-price sales €2,78. Fixed price therefore fetched about 18 % more — for this card patience with a set price is the better route.
What will I get for Professor's Research Crown Zenith 150/159 if I want to sell quickly?
Half of all sales fell between €2,09 and €4,05, with a median of €2,63. 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 Professor's Research Crown Zenith 150/159 unrealistic?
The cheapest genuine sales were around €1,74. Offers well below €1,04 are typically fakes, mislabelled cards or a different variant — ask for photos of all four borders and a close-up of the surface.
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.
