Frequently asked questions
Is it worth grading Zekrom GX SM Black Star Promos SM138/248?
A PSA 10 currently sells for about £1,531, raw the card sits at £10.53 — 145,4× as much. Mathematically, submitting returns £1,531 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.
Auction or Buy It Now — which gets more for Zekrom GX SM Black Star Promos SM138/248?
Across 5 auctions the median was £9.78, across 54 fixed-price sales £11.05. Fixed price therefore fetched about 13 % more — for this card patience with a set price is the better route.
What will I get for Zekrom GX SM Black Star Promos SM138/248 if I want to sell quickly?
Half of all sales fell between £9.77 and £14.91, with a median of £11.20. 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 Zekrom GX SM Black Star Promos SM138/248 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.
