Is it worth grading Mew BW Black Star Promos BW98/101?
A PSA 10 currently sells for about £388.97, raw the card sits at £140.57 — 2,8× as much. Mathematically, submitting returns £388.97 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 Mew BW Black Star Promos BW98/101?
Across 39 auctions the median was £75.64, across 58 fixed-price sales £116.41. Fixed price therefore fetched about 54 % more — for this card patience with a set price is the better route.
What will I get for Mew BW Black Star Promos BW98/101 if I want to sell quickly?
Half of all sales fell between £56.24 and £199.89, with a median of £79.92. 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 Mew BW Black Star Promos BW98/101 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.
