Sealed Pokémon products: value, authenticity and storage
Unopened products are a collecting market in their own right. A booster box from 2016 now costs many times its retail price — but only if it's genuinely sealed and has been stored well.
Which products go up in value?
Booster boxes and elite trainer boxes from popular sets rise the most, especially once the print run ends. Tins and blisters less so, because there are more of them. Special sets (Evolutions, Hidden Fates, 151) are the well-known outliers.
Spotting a genuine seal
Check the factory shrink wrap: original wrap has neat, slightly irregular seams and, on newer products, a Pokémon logo in the film. Resealed plastic is tight and smooth. Check the weight too, and make sure the box hasn't been crushed.
Storage
Dry, dark and at room temperature, away from sunlight (fading) and moisture. Stand boxes upright and don't stack them; a dent in the wrap lowers the price immediately.
Buying and selling
Compare with the sale prices in the TCG House catalogue: sealed products have a Cardmarket sale price just like cards. You can list them on the marketplace directly; the buyer pays through TCG House and you receive the money as soon as the product has been confirmed.
Frequently asked questions
Is a sealed product a good investment?
Sometimes, but it's not guaranteed: reprints push prices down. Buy what you enjoy yourself; if it goes up, that's a bonus.
How can I tell if a booster box has been resealed?
By the wrap (too tight, no seam pattern), a weight that's too low and packs that aren't in factory order. If in doubt, don't buy.
