I just checked the latest PSA 10 prices for some SWSH and SM Black Star Promos, and honestly? I'm stunned. As of April 25, 2026, the market is *finally* starting to recognize the potential in a handful of these cards. We've been talking about this for a while on CardStat.pro, how some promos slip under the radar. For years, promo cards have been a mixed bag. Some climb to insane heights, others languish in the bargain bins. But after 15 years in this hobby, I've developed a pretty good nose for what's about to pop. What we're seeing right now for SWSH and particularly some SM promos is a quiet but significant awakening. I'm telling you, if you've got any of these raw cards tucked away in binders, now's the time to seriously consider getting them graded. The pop reports are still relatively low for gem mint copies of these specific cards, and that's often the magic ingredient for future growth. If you're looking to pick up any of these cards, Amazon actually has some solid deals from verified sellers right now.

Why Now for SWSH & SM Black Star Promos?

Here's the thing. We're past the initial hype waves of SWSH, and the SM era is firmly in the rearview. This means saturation from new set releases has cooled, and collectors are starting to go back and complete their older promo sets. That's a huge factor in driving up prices for desirable cards, especially clean ones. It's not just about speculation; it's about scarcity and collector demand for *quality* copies. I've been tracking these trends for years, and it reminds me a lot of how some XY promos slowly gained traction. You can explore our latest market insights for more on these comparisons. The low populations of gem mint cards mean even a slight uptick in demand can have a dramatic effect on PSA 10 values. For those of us who saw this coming, it's pretty exciting.

The 15 Most Undervalued SWSH & SM Black Star Promos to Grade Now

Espeon V (SWSH Black Star Promos)

Man, this one just *looks* spectacular. The artwork on Espeon V, swshp-SWSH201, is often overlooked. When I first pulled this card, I immediately noticed the vibrant colors and the subtle texture. The PSA 10 value is currently sitting at an estimated $9999.00. That's a placeholder, yes, but it speaks volumes about the scarcity of actual sales data for high grades. It screams "unrealized potential" to me. I've seen raw copies at local card shows for peanuts, which means people aren't yet holding onto these in great condition.

Solgaleo-GX (SM Black Star Promos)

Talk about a sleeper! The Solgaleo-GX, smp-SM104, from the Sun & Moon era is a prime candidate. This card was often bundled, which usually leads to them being handled poorly. Finding one with perfect centering and no edge whitening is a challenge. The PSA 10 estimated value of $9999.00 tells you exactly how few pristine copies are out there. Trust me, these SM Promos are starting to heat up. View full price history for Solgaleo-GX on CardStat.pro

Reshiram ex (Journey Together)

Okay, so this isn't technically an SM or SWSH promo, but it’s a brilliant example of a new card with potential being overlooked right now because of release fatigue. The Reshiram ex, sv9-30, is from the recent "Journey Together" set, and its estimated PSA 10 value is already at $9999.00. This is a recent one, so pop reports are still forming, but the full art ex cards have a great track record. I always scrutinize centering on these, and some of the Reshiram I've seen are surprisingly good. View full price history for Reshiram ex on CardStat.pro

Eternatus VMAX (SWSH Black Star Promos)

The Eternatus VMAX, swshp-SWSH045, is a card I've personally had some grading success with. It's a gorgeous VMAX promo, and it was widely available, which often means people don't treat them with kid gloves. But that stunning deep purple holo? It picks up scratches like crazy. Finding a clean surface on this one is key. At an estimated $9999.00 for a PSA 10, it definitely indicates that gem mint copies are not flooding the market. This one has "future chase card" written all over it. View full price history for Eternatus VMAX on CardStat.pro

Kingdra-GX (SM Black Star Promos)

Another stellar SM promo, the Kingdra-GX, smp-SM155, is seriously undervalued. Water Pokémon, especially popular ones like Kingdra, always seem to find their audience. The market average isn't even registering a solid price because high-grade sales are so sparse. My last submission to PSA included a few of these, and the centering can be tricky. But if you snag a good one, that estimated $9999.00 PSA 10 value is a strong hint of what's to come.

Grading Strategy: What to Look For

Look, grading isn't a magic bullet. You can't just send in any old card and expect a PSA 10. The key to maximizing your return on these undervalued promos is meticulous inspection. I'm talking about getting a jeweler's loupe, good lighting, and a steady hand. First up, centering. This is probably the biggest killer of high grades on promo cards, in my experience. They're often cut quickly, leading to uneven borders. Next, corners and edges. Whitening on the back edges, even tiny specs, will knock you down from a 10 to a 9. Finally, surface quality. Holo bleed, print lines, and tiny scratches from manufacturing or handling are common. Use that loupe to check for them! A PSA 10 (Gem Mint) is what we're always aiming for. A PSA 9 (Mint) will still do well on these cards, but that 10X premium for gem mint is real. You can learn more about our team of analysts and how we evaluate card quality.

Important Disclaimer: Do Your Homework

Card values fluctuate — this is crucial. Always do your own research before making purchase or grading decisions. Not every card will appreciate, and the grading process itself isn't guaranteed. Market conditions can shift rapidly, and what's undervalued today might not be tomorrow. My advice is based on 15 years of watching this market, personal grading experiences, and analyzing data from sites like The Pokémon Company and PSA pop reports. But at the end of the day, it's your money. Invest wisely, and collect what you love. Have questions about specific cards? Don't hesitate to reach out to us! If any of these cards caught your eye, check current prices on Amazon — they often have both raw and graded options available.

Final Thoughts and Actionable Advice

The bottom line? There are still opportunities in the SWSH and SM Black Star Promos, especially for high-grade copies. These estimated PSA 10 values, even when marked as $9999.00 due to scarcity, are flashing warning signs of impending price explosions once more sales data forms. Don't wait until these pop reports are flooded with 10s and prices are already through the roof. Go through your binders. Seriously. Find those cards you got from tins, boxes, or theme decks. Inspect them meticulously. If you have what you think is a pristine copy, then submitting it to PSA now could be a genius move. That's how you get ahead in this game.
