Pokémon 151 Japanese Booster Box: a Pokémon release from The Pokémon Company, scored here on appreciation, liquidity, accessibility and risk. It's filed as a hold-sealed play rather than something to rip, and those two strategies want opposite things — holding wants time and shrinking sealed supply, ripping wants peak demand right now.
Appreciation 88 with liquidity 85 is the combination worth looking for: room left to run, and a market deep enough that you could act on a change of mind. It's also the combination that attracts the most competition, which is usually why accessibility is the score that suffers.
Accessibility of 25 is the catch. That score tracks whether you can buy near MSRP or you're already paying a premium to someone else, and at 25 you are paying up. A box with real upside bought at double MSRP is a worse purchase than an ordinary one bought at retail.
Set against the 12 Pokémon sealed products scored here, its appreciation of 88 ranks 4th of 12, liquidity 85 ranks 7th, accessibility 25 ranks 8th, and risk 12 is the 2nd-lowest. The closest thing to it on the numbers is Pokémon Scarlet & Violet 151 English ETB, which scores 85 and 88 on the same two axes — if you're weighing one against the other, the difference is in the reasoning rather than the scores.
Two years gives the situation time to develop past its first impression, which is usually when the price is set by whoever shouted loudest. It also means two years of not touching it, including through the stretch where it looks wrong.
At 12, this is one of the calmer entries in here. Read that as relative: the floor under any card is whatever the next person will pay, and that number can move a long way in a month.
Every entry gets four separate scores instead of one grade, because a single grade hides the thing you needed. Full explanation in the guide: which sealed boxes return more than they cost.
