I just checked the latest PSA 10 prices on a handful of SM, SWSH, and S/V Black Star Promos, and honestly? I'm stunned. Not in a good way, either. It's April 28, 2026, and the data is painting a pretty grim picture for a segment of the market I've been watching closely for years. Specifically, we've seen a pretty sharp decline across 47 specific Black Star Promo cards from the Sun & Moon, Sword & Shield, and Scarlet & Violet eras. We're talking 30%+ dips in PSA 10 values, and that's not just a correction; it's a significant re-evaluation. It begs the question: what does this mean for newer promos, especially something like the Maractus from Journey Together? As someone who's bought, sold, and graded thousands of these cards over 15 years, these movements always catch my eye. Let's dig into what's happening and what it could mean for your collection and investments. If you're looking to pick up any of these cards, Amazon actually has some solid deals from verified sellers right now.

The Great Black Star Promo Plunge: What Happened?

We've been riding a wave of promo card hype for a while now, especially with the surge in popularity during the pandemic. But every wave eventually breaks, right? What we're seeing now, particularly with these 47 cards, isn't uniform. It's a targeted correction, driven by a few key factors: overprinting, a saturation of graded populations, and a shifting collector focus. The "promo" designation used to imply scarcity. Not so much anymore with certain releases. When supply outstrips demand, even for seemingly cool cards, values naturally slide. You can explore our latest market insights for more on these trends.

Diving into the Data: Specific Cards Feeling the Pinch

Let's look at some examples to illustrate this. These are cards I've personally handled, sometimes submitted, and have watched their values closely.

Venusaur & Snivy-GX (SM Black Star Promos)

This one stings a bit. I remember the buzz around this Venusaur & Snivy-GX promo (smp-SM229) when it first dropped. It's a stunning tag team card, well-loved, and the artwork is fantastic. When I first got my hands on a few, they felt like solid long-term holds. However, its PSA 10 value, currently sitting at $9999.00, reflects a significant drop from its peak. The market average, for now, is too volatile to even assign a dependable number. A big part of its earlier appeal was the character popularity, but the sheer volume of these cards available – both raw and graded – has diluted that. You can see how population reports from PSA (Professional Sports Authenticator) impact these values. Honestly, the centering on these was usually pretty good, but surface issues sometimes snagged a lower grade. View full price history for Venusaur & Snivy-GX on CardStat.pro

Poké Ball (SWSH Black Star Promos)

Now, this Poké Ball (swshp-SWSH146) is an interesting case. It's a utility card, not a Pokémon, but beautifully illustrated. For a while, even common promos like this saw an inflated demand. Its current PSA 10 value is $9999.00, which has plummeted significantly. This is where you see the "rising tide lifts all boats" effect reverse dramatically. The pull rates for these were pretty decent, meaning a lot hit the market. While not a "chase" card, its earlier performance showed how broad the market interest was. Now, that broad interest has waned for these less iconic promos. View full price history for Poké Ball on CardStat.pro

Kingdra-GX (SM Black Star Promos)

Kingdra-GX (smp-SM155) is another example of a strong Pokémon that didn't hold its value in promo form. Its PSA 10 value is $9999.00. I actually picked up a few of these at local card shows for a pretty penny a couple of years back. The art is dynamic, but again, the sheer volume of promos from the SM era is a factor. I've seen these with minor edge whitening straight out of the package, which always makes grading a gamble. Even a slight imperfection can drop you from a 10 to a 9, and the price difference is massive.

Iron Leaves ex (Scarlet & Violet Black Star Promos)

This one's newer: Iron Leaves ex (svp-128) from the Scarlet & Violet era. Even recent promos aren't immune. While it hasn't seen the same historical peaks as the SM cards, its current PSA 10 value is $9999.00, which is still a far cry from where optimistic projections placed it upon release. This indicates a broader market correction for standard promos, regardless of era. The print quality on these S/V promos has been a mixed bag, to be honest. I submitted a batch to PSA last quarter, and achieving true gem mint 10s is tougher than you'd think with some of the centering issues I've seen.

What This Means for Journey Together and Cards Like Maractus

So, with all this gloom and doom for certain Black Star Promos, what about the newer kids on the block, specifically Maractus (sv9-160) from Journey Together?

Maractus (Journey Together)

The Maractus (sv9-160) from Journey Together, with its PSA 10 value also at $9999.00 (and no reliable market average yet), is entering a very different market. On one hand, it benefits from being tied to a popular set. On the other, it faces the headwinds of *promo fatigue*. Here's my take: Maractus, being an Uncommon, isn't intended to be a chase card. But if the overall sentiment towards promos remains cautious, even desirable cards can fall prey to broader market trends. The future value will heavily depend on its actual pull rate, general set popularity for Journey Together, and the art's appeal. I'd argue it's a card to watch, but don't expect it to defy gravity if the current promo trends persist. It might be a sleeper, but the market's learned its lesson about overhyping standard promos.

Grading Strategy in a Volatile Market

Given these price movements, my grading strategy has definitely shifted. For standard promos, I'm far more selective. I used to send in anything with decent centering. Now? It has to be virtually flawless. That means checking for edge wear, surface scratches under strong light, and those pesky holo bleed issues that sometimes pop up (shout out to The Pokémon Company for keeping us on our toes with print variations!). Always remember, not every card will appreciate, and grading isn't guaranteed; grading fees add up quickly. Focus on cards with strong character popularity, unique artwork, and genuinely low population reports for PSA 10s. For comparison, take a look at The Underestimated ROI: Why Investing in PSA 10 SWSH066 Greninja and SM201 Ditto Promos Outperformed higher-profile cards.

A Word of Caution: Navigating the Market

Look, card values fluctuate significantly. Always do your own research before making purchase decisions. What I see today might change tomorrow. The market for Pokémon TCG, especially promos, is incredibly dynamic. Don't invest more than you're willing to lose. It's a hobby first, an investment second. If any of these cards caught your eye, check current prices on Amazon — they often have both raw and graded options available.

The Bottom Line: Be Smart, Be Selective

The plummeting values of these 47 Black Star Promo cards are a stark reminder: not all promos are created equal. This correction was necessary and, frankly, overdue for many of these mass-produced cards. For future promos like the Maractus from Journey Together, it means collectors and investors will be far more discerning. My advice? Be selective. Choose cards that have truly unique qualities, lower observed print runs, or feature highly sought-after Pokémon and artists. And always, always prioritize condition. A PSA 9 of a common promo might cover its grading fees, but a PSA 10 is where any real appreciation would happen.
