Is it worth grading Grass Energy Base Set 99/102?
A PSA 10 currently sells for about £206.43, raw the card sits at £11.90 — 17,3× as much. Mathematically, submitting returns £206.43 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 Grass Energy Base Set 99/102?
Across 47 auctions the median was £12.11, across 49 fixed-price sales £11.16. There is no meaningful difference — what matters here is how fast you want to sell.
What will I get for Grass Energy Base Set 99/102 if I want to sell quickly?
Half of all sales fell between £3.82 and £12.11, with a median of £6.38. 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 Grass Energy Base Set 99/102 unrealistic?
The cheapest genuine sales were around £1.45. Offers well below £0.87 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.
