I’ve been collecting Pokemon cards for over 25 years and I still got caught off guard by this one.

Scarlet & Violet 151 came out in September 2023. Two and a half years ago. It had its hype cycle, the restocks came, prices cooled, and most people moved on to whatever the next shiny set was. I figured the 151 SIRs had found their floor. Comfortable holds. Nothing wild.

Then last week happened.

The Numbers Are Insane

The Big Kanto Three Special Illustration Rares from 151 just posted some of the most aggressive single-week price jumps I’ve seen in the modern era:

  • Charizard ex (199/165): From $348 to $443. That’s a $94 spike. 27% in one week.
  • Blastoise ex (200/165): From $150 to $216. A $66 jump. 44% in one week.
  • Venusaur ex (198/165): From $82 to $145. That’s a 77% increase. On a Venusaur.

Read that last one again. Venusaur - the starter literally nobody picked as a kid - just almost doubled in price in seven days.

Something real is happening here.

Why Now? It’s Not Just Anniversary Hype

The obvious answer is the 30th anniversary celebration. Pokemon Presents dropped February 27, we got the Gen 10 reveal with Pokemon Winds and Waves, FireRed and LeafGreen hit Switch Online, and suddenly the entire internet remembered that Kanto exists. Social media was flooded with first-gen nostalgia. Of course prices moved.

But the anniversary explains maybe half of this. Here’s what’s actually driving the surge underneath the noise:

Supply dried up faster than anyone expected. 151 was printed heavily at launch. Everyone knew that. The “151 is overprinted” take was the popular one for over a year. What people missed is that 151 was also opened heavily. The set had only 7 SIRs. Pull rates were decent. So collectors ripped an enormous amount of product chasing those hits. That sealed supply that was supposedly everywhere? A lot of it got consumed.

Retail availability for 151 booster bundles and ETBs has been inconsistent at major stores for months now. When the casual buyer can’t just grab a box at Target anymore, secondary market prices start reflecting real scarcity instead of perceived abundance.

The collector demographic for 151 is different. Most modern sets appeal primarily to competitive players and set completionists. 151 hits a third group that’s way bigger than both: nostalgia collectors. People who haven’t bought a Pokemon card since 2001. People whose kids are now old enough to open packs with them. (I’m literally one of these people. Tanner and I crack packs together and the 151 SIRs are some of his favorites because he recognizes the Pokemon.)

That demographic doesn’t follow set rotations or meta shifts. They buy based on emotional connection. And nothing triggers emotional spending quite like the original 151 Pokemon printed on gorgeous full-art cards.

Mega Gengar ex set the ceiling. Here’s something the market watchers caught early: the Mega Gengar ex SIR from Ascended Heroes hit $979 last week. Nearly a thousand dollars for a modern card that’s been out for less than two months. When collectors see a modern SIR approaching four figures, it recalibrates what they think the best SIRs from the best set should be worth. If Mega Gengar can touch $1000, why is the Charizard from 151 - arguably the most iconic card in the modern era - sitting at $350? That gap felt wrong, and the market corrected hard.

Should You Buy In Right Now?

Here’s where I’m going to be honest and probably make some people mad.

If you don’t already own these cards, buying right now is a gamble. Not because 151 won’t keep appreciating long term. I think it will. But because you’d be buying into peak FOMO, and FOMO pricing always overshoots before it settles.

The week-over-week spikes we’re seeing are not sustainable. A 77% weekly increase on Venusaur doesn’t become a 77% increase next week. That’s not how markets work. There will be a pullback. How much? Nobody knows. But buying at the literal peak of a parabolic run is how collectors get stuck holding cards that drop 20-30% within a month.

My actual strategy right now:

Hold everything I have. My 151 SIRs aren’t going anywhere. This is a 3-5 year hold minimum. The 30th anniversary is just the beginning of what I think will be a sustained appreciation cycle for anything Kanto-related. Gen 10 is coming on Switch 2 in 2027. That’s another massive wave of attention for Pokemon as a whole, and 151 will benefit again.

Wait 4-6 weeks before buying singles. The anniversary spike will cool. The Perfect Order release on March 27 will absorb a chunk of collector spending. When the market’s attention shifts to the new set, 151 prices should settle back to a new baseline that’s higher than pre-spike but lower than this week’s peak. That’s when I’m looking to add.

Sealed 151 is a different conversation. If you can find a Pokemon 151 booster bundle or Pokemon 151 ETB at or near MSRP? Buy it. Don’t think about it. Sealed 151 at retail pricing is already gone from most stores and it’s not coming back. This is one of those sets where sealed product five years from now will look like the people who sat on Evolutions boxes, especially if you got in on a Pokemon 151 booster bundle. The market just hasn’t fully priced in the supply reality yet.

The Cards I’m Watching

Beyond the Big Three, here’s what’s moving in 151 that hasn’t gotten enough attention:

Charmander (168/165) Illustration Rare - This card is part of the same evolution art series as the Charizard SIR. It’s been quietly climbing and benefits from the same nostalgia wave at a fraction of the price.

Mew ex (151/165) - The card that literally defines the set. If you believe in 151 long term, Mew ex is probably the most underpriced chase card in the set relative to its importance.

Japanese 151 SARs - The Japanese versions of these same cards are trailing the English price movement by about 2-3 weeks. If you believe the English cards are fairly priced at current levels, the Japanese equivalents still represent relative value.

The Bigger Picture

What’s happening with 151 isn’t really about one set having a good week. It’s about the market waking up to something that was hiding in plain sight: Scarlet & Violet 151 is the most important Pokemon TCG set released in the modern era.

Not the most valuable. Not the most competitive. The most important. It’s the set that brought back every 30-something who hadn’t touched a Pokemon card in two decades. It’s the set that parents buy to open with their kids because they recognize every single Pokemon in it. It’s the set that bridges 1999 and 2026 in a way nothing else has.

The 30th anniversary just reminded everyone of that. But the cards were always going to get here. The question was always when, not if.

I’ll be tracking 151 prices weekly from here. The next month is going to be wild with Perfect Order launching and attention splitting between the new Mega evolutions and the Kanto nostalgia wave. If you’re holding 151, sit tight. If you’re looking to buy, be patient.

The worst thing you can do right now is panic buy because of a number someone posted on Twitter. The second worst thing is sell because you think this is the top.

It’s not the top. It’s also not the right time to chase. Both of those things can be true at once.

The Nostalgia Premium Is a Multiplier Not an Accident

Every time people try to explain why 151 SIRs are expensive, they point to nostalgia like it’s some vague emotional force. But nostalgia in the Pokemon card market is a specific, measurable pricing factor. Cards featuring Generation 1 Pokemon consistently sell for more than cards of comparable rarity featuring later-generation Pokemon. This has been true for years and it’s getting MORE pronounced as the generation that grew up with the original 151 enters their peak earning years.

Think about who’s buying these cards. It’s not teenagers. It’s people in their late twenties to early forties who remember the original Kanto Pokemon from their childhood and now have real disposable income. When someone who makes six figures sees a beautiful illustration rare of their favorite childhood Pokemon, the price tag hits differently than it does for a college student. The 151 SIRs are priced for that buyer and that buyer has money to spend.

The Print Run Question

Here’s the thing nobody can confirm but everybody suspects: 151’s effective supply may be tighter than people initially assumed. The set launched, sold through aggressively, got a restock wave, sold through again, and now sealed product is trading above retail in most places. When sealed product holds a premium, it usually means supply is tightening. And when supply tightens on a set with chase cards that people already want, prices accelerate.

I’m not going to pretend I have insider knowledge about print runs. Nobody outside TPCi knows those numbers. But I can look at sealed product pricing as a proxy for availability, and what I see tells me 151 isn’t being reprinted endlessly the way some modern sets are. Whether that’s a deliberate decision or just production capacity, the result is the same: the cards are getting harder to pull because there are fewer packs to pull them from.

What Would Make Me Sell

I’m holding my 151 SIRs right now but I’m not married to them. Here’s what would change my mind: a confirmed major reprint announcement, a broader market correction that takes the whole hobby down, or a price spike so aggressive it starts feeling disconnected from fundamentals. If I see cards jumping twenty or thirty percent in a single week with no news catalyst, that’s usually FOMO-driven buying and those moves correct.

The cards I’d sell last are the ones with the strongest nostalgia anchors — the iconic Kanto Pokemon that everyone recognizes. Those have pricing floors that more obscure 151 entries don’t. Knowing which tier your card sits in matters a lot when you’re deciding whether to hold or take profits.

The Risk Nobody Wants to Acknowledge

I’ve spent this entire article explaining why 151 SIRs have gotten expensive and why the fundamentals suggest continued strength. But I’d be dishonest if I didn’t talk about the risks, because there are real ones.

The biggest risk is a major reprint. TPCi has surprised the market before with reprint waves that were bigger than expected, and if they decide 151 deserves another significant production run, supply increases and prices come down. I don’t think this is likely based on how they’ve handled the set so far, but I also wouldn’t bet my retirement on it.

The second risk is broader market fatigue. The Pokemon card market has been running hot for years now. Markets don’t run hot forever. If there’s a correction — driven by economic conditions, hobby fatigue, or just a natural cycle — 151 SIRs will come down with everything else even if their relative position stays strong. No card is immune to a market-wide pullback.

The third risk is the one nobody talks about: you overpay because you read articles like this one and convince yourself the only direction is up. Nothing only goes up. If you’re buying 151 SIRs, buy at a price you’re comfortable holding through a drawdown. If you can’t stomach a thirty percent dip without panicking, you’re over-allocated and you should size down. That’s not bearishness — that’s risk management, and the collectors who practice it consistently are the ones still in the hobby five years from now.

I’m bullish on 151 SIRs as a medium-term hold. I think the fundamentals support continued strength over the next twelve to twenty-four months, with the 30th anniversary as a potential catalyst for another leg up. But I also recognize that I could be wrong. Markets are humbling. The best I can do is make decisions based on what I see today, manage my risk responsibly, and adjust when the data tells me to. If you’re holding 151 SIRs, I think you’re in a good position. If you’re thinking about buying, do it with eyes open and a budget you can afford to be patient with.
