Frequently asked questions

Is it worth grading Grass Energy Base Set 99/102?

A PSA 10 currently sells for about £74.53, raw the card sits at £1.20 — 62,0× as much. Mathematically, submitting returns £74.53 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.

What will I get for Grass Energy Base Set 99/102 if I want to sell quickly?

Half of all sales fell between £0.89 and £1.70, with a median of £1.27. 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 Grass Energy Base Set 99/102 unrealistic?

The cheapest genuine sales were around £0.74. Offers well below £0.44 are typically fakes, mislabelled cards or a different variant — ask for photos of all four borders and a close-up of the surface.

Is the English or the German Grass Energy Base Set 99/102 worth more?

From real sales: English £1.20 (70), German £1.08 (13). English fetches about 12 % more.

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.
