FAQ

Frequently asked questions

Is it worth grading Grumpig Crystal Guardians 20/100?

A PSA 10 currently sells for about $862.36, raw the card sits at $14.23 — 60,6× as much. Of 123 copies already graded, 42 % received a 10 and 38 % a 9. Mathematically, submitting returns $496.84 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. The grade distribution comes from the PSA Population Report; people pre-sort before submitting, so your own hit rate may differ.

What will I get for Grumpig Crystal Guardians 20/100 if I want to sell quickly?

Half of all sales fell between $1.83 and $6.75, with a median of $2.39. 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 Grumpig Crystal Guardians 20/100 unrealistic?

The cheapest genuine sales were around $1.12. Offers well below $0.67 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.
