Sealed product: two thirds went up, and the fallers were all brand new.

There's an old argument in this hobby. Do you hold sealed boxes, or do you hold singles? I can't settle it with nine weeks of data, but I can show what happened in those nine weeks.
I took every sealed English product worth $10 or more on July 30 and checked it again on October 1. That's 1,970 products: booster boxes, tins, collection boxes, theme decks, single packs.
- The typical sealed product gained 3.4%.
- 67% of them went up.
- For comparison, the typical English single over $5 gained 4.2%, and 64% went up.
So, basically a tie. Sealed was a little steadier, singles gained a little more. Neither side of that argument gets to win on this.
What went up
| Product | July 30 | October 1 | Change |
|---|---|---|---|
| Poke Ball Tin, Luxury Ball | $34 | $90 | +166% |
| Tsareena GX Box (Burning Shadows) | $92 | $200 | +117% |
| Poke Ball Tin, Dive Ball | $90 | $180 | +100% |
| Supreme Victors Booster Pack | $375 | $717 | +91% |
| Dusk Mane Necrozma Premium Collection | $166 | $290 | +75% |
| Flashfire Theme Deck, Mystic Typhoon | $40 | $70 | +75% |
Not a booster box in sight. It's tins, collection boxes and a theme deck. The stuff people opened without thinking, because it wasn't the thing you were supposed to keep sealed. That's exactly why sealed copies are hard to find now.
I'd take the tin numbers with some salt. Odd products like these sell rarely, so one sale can double the price. The direction is real. The exact percentage, less so.
What went down
| Product | July 30 | October 1 | Change |
|---|---|---|---|
| First Partner Illustration Collection Case (Series 3) | $539 | $160 | -70% |
| First Partner Illustration Collection (Series 3) | $65 | $26 | -60% |
| 30th Celebration Tech Sticker Collection | $194 | $81 | -58% |
| Pitch Black 3-Pack Blister Case | $1,220 | $540 | -56% |
| 30th Celebration Booster Pack | $32 | $14 | -55% |
| 30th Celebration ex Tin, Sylveon ex | $150 | $69 | -54% |
Every one of those is a recent release, most of them from this year. This is the launch pattern. A product comes out, the first copies sell at a premium because nobody can find it, then the shelves fill up and the price falls to what it should have been. Paying the first-week price cost people more than half their money in two months.
What I take from it
- Don't buy sealed in the first weeks of a release unless you plan to open it.
- The sealed product that goes up is the kind people didn't bother to keep.
- Over a short stretch, sealed and singles moved about the same. The sealed argument is a multi-year argument, and I don't have multi-year data yet.
It's the same thing I found with singles: old sets went up and new sets went down. Sealed is just the boxed version of that.

- Old sets went up. New sets went down. Here is how lopsided it was.Nine weeks of nightly prices across 184 sets: 119 rose, 34 fell, and almost every faller was printed in the last two years.
- Japanese or English? The same Pokémon is not the same price.For 130 of 153 Pokémon, the typical English card costs more than the typical Japanese one. Umbreon is the widest gap. Pikachu is one of the few exceptions.
- One in five cards moved 20% in nine weeks. At every price.I expected cheap cards to be jumpy and expensive cards to be steady. The data says the jumpiness is about the same from $1 to $100 and up, and the reason is how few times a card actually sells.
