Dialga-GX

Our early read is $500 — the asking price on the one listing our last scan could verify as this exact card. We publish a full fair value once 6+ verified listings agree — until then, treat the early read as directional and check recent sold listings on eBay too.

As of our last sweep, 4 live eBay listings passed our identity checks for this exact slab, asking from $498 delivered (item + shipping). That's our radar's verified view, not all of eBay — listings without clear photos or a provable match don't count, and sellers list and delist all day. Every one we see is in the Available Now rail on this page.

It's the Dialga-GX from Ultra Prism, card number 100/156, professionally graded 10 by PSA (Professional Sports Authenticator). The grade and cert number on the slab make this exact card identifiable and priceable — that's why our radar tracks graded copies only.

Grade is most of the story: a single grade step can move the price dramatically, and even within one grade, listings differ on seller reputation, photo quality, and shipping. That spread is exactly what our radar watches — when someone lists a legitimate copy well below the going rate, it shows up on our deal board. Card grading, explained simply →

Right now our Deal Radar sees 4 live listings for this card priced at least 10% below the fair value we compute — they're badged in the Available Now rail on this page. Every purchase happens on eBay, with eBay buyer protection.
