I just checked the latest PSA 10 population reports for some of our beloved promo cards, and honestly? As of April 23, 2026, I'm a bit stunned. We're talking about cards that, just a couple of years ago, everyone thought were slam-dunk investments. And now? Not so much. The market has shifted, folks. Big time. What we thought were easy wins in the SM and SWSH Black Star Promo categories — especially those gorgeous GX and V cards – have, for a variety of reasons, absolutely cratered in value once they came back from grading. It's a tough pill to swallow if you were banking on these. It’s a perfect example of why you can't just follow the hype. You've gotta understand the underlying market mechanics, the print runs, and what makes a card *truly* rare and desirable in a gem mint slab. (If you're curious about deeper market dives, definitely explore our latest market insights.) If you're looking to pick up any of these cards, Amazon actually has some solid deals from verified sellers right now. Now, let's dive into some specific examples.

The Great Grading Crash: When Promos Go Bust

Here's the thing about promos: they're distributed differently than main set cards. Sometimes that means scarcity; other times, it means oversaturation. When you combine high distribution with lax quality control and a surge in grading submissions, you get exactly what we're seeing. The PSA pop reports are telling a story of too much supply, especially for cards that everyone *thought* would be rare. Many of these simply don't have the long-term investment potential of some overlooked Scarlet & Violet promos I've written about previously, like in this post. The biggest culprit? The sheer number of submissions. Everyone and their grandma sent these in, hoping for a quick buck. And why not? PSA 10s historically command a premium. But when too many people have the same idea for the same card, the market responds. (For more on grading, check out PSA's official site.) Let's look at some specific disasters.

Primarina-GX (SM Black Star Promos)

Ah, the Primarina-GX (smp-SM39). When this beauty first dropped, everyone was buzzing. It was one of the early GX promos, had a stunning full-art treatment, and was given out with the Primarina-GX Box. Personally, I pulled a few of these back in the day and thought they were gorgeous. But here's the kicker: the print quality on these was notoriously inconsistent. Centering was often off right out of the box, and subtle holo scratching was common due to how it was packaged. With a PSA 10 value of $9999.00 today (which, let's be real, is a placeholder because the *actual* market is so thin these days at that price point), it reflects more aspiration than reality. The market average? N/A — meaning there simply aren't enough active sales at a significant price point to even track. This card has been an absolute brick for graded value, despite its visual appeal.

Venusaur & Snivy-GX (SM Black Star Promos)

Now we come to the Venusaur & Snivy-GX (smp-SM229). This card was part of the "Tag Team Powers Collection," a set that promised big things with the return of "Tag Team" Pokémon. Everyone loved the artwork, and it felt like a nostalgic nod with Venusaur. However, the supply for these was astronomical. The print run for these Tag Team Collections was *massive*, and consequently, so was the number of cards available to be graded. A lot of collectors also found slight edge wear or minor whitening straight out of the package. With a PSA 10 value of $9999.00 – another essentially untrackable price point due to market liquidity – it's clear this one didn't pan out. I’ve seen these sell at local card shows for a fraction of what people hoped in PSA 9, let alone a mythical 10. View full price history for Venusaur & Snivy-GX on CardStat.pro

Hop's Zacian ex (Journey Together)

Okay, so let's talk about the *real* "Journey Together" mistake: Hop's Zacian ex (sv9-176). This card came out of the Scarlet & Violet era, and while it's aesthetically pleasing, it suffers from the same over-supply problem. It was widely available, and print quality for these recent sets has been fairly consistent, meaning a lot of people were able to pull clean copies. What catches my eye is that while this card looks fantastic, the sheer volume of high-grade copies available has deflated its value. A PSA 10 value of $9999.00 indicates a theoretical high, but the market barely registers consistent sales. It’s a good looking card, no doubt, but the investment return for grading was just not there.

Iron Leaves ex (Scarlet & Violet Black Star Promos)

Another casualty of plentiful supply is Iron Leaves ex (svp-128), another Scarlet & Violet promo. These ex cards are visually impressive, often with great texture and vibrant colors. I remember thinking this one would hold its own. But like its predecessors, the distribution of these black star promos was wide, leading to a high pop count for gem mint examples. Collectors were excited, cracking open products and sending them straight to PSA. When the PSA 10 value is stuck at $9999.00 and the market average isn't even trackable, it's a clear signal that the card's graded value has been thoroughly diluted by supply.

Poké Ball (SWSH Black Star Promos)

Finally, we have the Poké Ball (swshp-SWSH146). This one is a bit different as it's an item card, but the principle remains. It was a promo given out in blisters or collection boxes, meaning it was very accessible. While it's a clean-looking promo and a staple image, its nature as a common promo means that tons of sealed products contained it. Everybody could get one, and many people did. As a result, the PSA 10 value being $9999.00 means, in practice, it’s not really selling at an investment-worthy price and likely never will. It's a prime example of a card that collectors love to have, but it's not going to make you rich graded.

Grading Strategy: What I've Learned (The Hard Way)

My personal grading experiences? They're full of lessons. I've submitted a batch to PSA last quarter that included a few of these types of promos, hoping for a miracle, and let’s just say they mostly came back as 9s. Why? Small imperfections. Often, it's subtle whitening on the back edges, or minor surface dimples you can only see under harsh light. Centering is another major killer for promos—they don't always get the same QC as regular set cards. The bottom line is that for a card to truly appreciate in a PSA 10, it needs a combination of factors: desirability, genuine scarcity *even at launch*, and good factory quality control. A high population of PSA 10s will almost always dilute value, regardless of how cool the card looks. Always check PSA pop reports *before* you grade, not after.

The Risk and Reward of the Hunt

Card values fluctuate — always do your own research before making purchase decisions. Not every card will appreciate, and grading isn't guaranteed to increase a card's value. Honestly, sometimes it costs you more than it's worth. Be realistic about what you have and what you want to achieve. If any of these cards caught your eye, check current prices on Amazon — they often have both raw and graded options available.

Final Thoughts: Grade with Purpose, Not Hope

So, what's my advice after 15 years in this wild hobby? Grade with purpose. Understand print runs, distribution methods (The Pokémon Company publishes release info), and the *actual* raw card condition. Don't fall for the trap of grading every nice-looking promo you pull. These SM and SWSH Black Star Promos, while beautiful, taught us a harsh lesson about supply and demand in the graded market. For future endeavors, remember that rarity isn't just about pull rates from booster packs; it's also about the number of *mint* copies that ultimately exist.
