Frequently asked questions
Is it worth grading Boost Shake Evolving Skies 229/203?
A PSA 10 currently sells for about $46.98, raw the card sits at $4.48 — 10,5× as much. Mathematically, submitting returns $46.98 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 Boost Shake Evolving Skies 229/203?
Across 12 auctions the median was $1.50, across 55 fixed-price sales $4.10. Fixed price therefore fetched about 172 % more — for this card patience with a set price is the better route.
What will I get for Boost Shake Evolving Skies 229/203 if I want to sell quickly?
Half of all sales fell between $2.90 and $4.86, with a median of $3.83. 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 Boost Shake Evolving Skies 229/203 unrealistic?
The cheapest genuine sales were around $1.50. Offers well below $0.90 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.
