Is it worth grading Koffing Base Set 51/102?
A PSA 10 currently sells for about €106,09, raw the card sits at €27,20 — 3,9× as much. Mathematically, submitting returns €106,09 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 Koffing Base Set 51/102?
Across 7 auctions the median was €37,91, across 9 fixed-price sales €26,24. Auctions therefore fetched about 44 % more — worth it mainly for sought-after cards with several bidders.
What will I get for Koffing Base Set 51/102 if I want to sell quickly?
Half of all sales fell between €14,87 and €27,89, with a median of €25,36. 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 Koffing Base Set 51/102 unrealistic?
The cheapest genuine sales were around €13,03. Offers well below €7,82 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.
