Our Most Interesting Purchases In April: We're All In On Stephon Castle
Looking at recent purchases of numbered cards, rare Kaboom! parallels, and the numbers behind them.
In our Market Update posts, we usually discuss the cards that we’re targeting most frequently. Recently, this has included Topps Chrome Shohei Ohtani, Prizm Victor Wembanyama, and Pokémon Ascended Heroes cards.
We continue to buy lots of these, but in this post, I want to highlight some of the more unique cards we’re buying, including some rare numbered cards that you don’t see on the market everyday.
These cards are often interesting, because it’s not always easy to determine the exact market price of them. Additionally, you have less competing listings on the market. This gives you the flexibility to price these cards higher, but you also run the risk of going weeks or months without selling them.
Regardless, let’s take a look at some of these cards.

1. 2025 Phoenix Color Blast Jaxson Dart
The Expected Value math on the 2025 Phoenix Color Blast Football cards is generally solid, but not amazing. We bought this at about 40% Expected Profitability, which isn’t bad but it’s not quite as high as Downtown Football was a few months back.
This is also interesting because the Gem Rate on Phoenix Color Blast was very high last year, but overall it’s below 50% this year (this card in particular is at 50.7%). I haven’t had enough of these in hand yet to know exactly what’s driving this, although from looking at listings I can tell the centering is less consistent in 2025 than it was in 2024.
Another interesting variable here is that 2025 Topps Chrome Football just recently released. We’ll see what kind of impact this has on Panini pricing. From what I’ve seen on the market, it seems that Phoenix inserts and case hits in general were very sparsely produced this year, which should help it retain value.
On Jaxson Dart specifically, I find him to be the most interesting quarterback from the 2025 class. The Giants are trending up and hopefully star receiver Malik Nabers will be healthy soon, Dart has shown flashes of being great (but has had some really bad games as well), and John Harbaugh is coming in next season as his new coach. I think the sky is the limit, but the downside is high too. A little high risk, high reward can be fun.
2. 2023 Phoenix White Lazer Victor Wembanyama /150
I’ve never actually seen this card before, but basically anything Wembanyama is worth looking at these days. There’s not a lot of historical sales, but I was able to estimate a PSA 10 Value of $700 and a Gem Rate of 74.3%. This was a pretty easy decision to buy for $245. The card looks clean too.
There’s only one of these currently on the market, and it’s a PSA 10 listed at $1,250. That’s a good sign for us as Wembanyama starts to dominate in NBA playoff games.
3. 2024 Panini Revolution Kaboom! Stephon Castle
Stephon Castle has been on my radar as a potential target, but we just hadn’t pulled the trigger until now. Mainly because there’s only a handful of his cards that are expensive enough raw for us to consider (we generally target raw cards worth $100 or more).
With that said, this market is interesting, because based on my estimates we’ll actually make solid money on this card if it grades a 9. We estimated the PSA 10 Value/PSA 9 Value/Gem Rate of this card at $3,900/$2,200/32%, but bought it for just $1,500. This is a real needle mover for us, as we only buy a few cards in this price range per month.
4. 2019 Bowman Chrome Gunnar Henderson Blue Wave Auto /150
Honestly, this is the kind of purchase that gets me fired up. I think Gunnar is an underrated player, and Bowman Chrome Draft is one of my favorite products. Add in that this card design looks amazing and it’s numbered 1/150, and I’m all in.
Of course, this is still a business decision, and the numbers supported this one. We estimated the market at $2,500/$1,250/52%, and bought the card for about $1,150.
