New PSA 10s Have a Supply Problem

Two slabs tell you where the graded market is right now. Over the last three weeks, the PSA 10 population of Chaos Rising's Mega Greninja ex went from 179 to 458 while its sale prices fell from $1,399 to the mid $800s. Over the same stretch, Raikou Gold Star added exactly zero new gems, and its sales climbed from the $9,000s to as high as $17,100.

Same market. Same three weeks. The difference is the supply curve underneath the slab.

The markdowns are concentrated in fresh gems

Seven of the ten biggest 30-day fallers on the graded board come from one set: Ascended Heroes.

Mega Gengar ex is the deepest one. It's down 30% over the last 30 days to $291, and that markdown printed on 290 sales in the past month, the highest trade count anywhere on the board. Real volume, real repricing. The set's Pikachu ex Special Illustration Rare (SIR) closed between $1,100 and $1,325 in the back half of June; last week it mostly went for $960 to $995. Lillie's Clefairy ex sold at $640 to $750 in mid-June and sits around $500 now, off 29% on the month.

Here's the part that got us. Ascended Heroes came out at the end of January. Five and a half months later the gem supply is still stacking: Mega Gengar's PSA 10 population went from 3,924 to 5,603 in the eighteen days we measured. That's 43% more gems in under three weeks, on a set whose launch chase is long over.

Chaos Rising is the same script on fast-forward. The first Mega Greninja ex gems came back from the graders on June 28 and sold for $1,300 to $1,400. Since then the population has climbed from 179 to 458, and last week's sales ran $800 to $950.

The frozen side re-rated

Every verified gainer on the graded board sits on a supply curve that finished growing years ago.

Raikou Gold Star from Unseen Forces sold five times in May, all between $8,900 and $10,000. The four June sales came in at $12,000, $14,000, $15,000, and $17,100. Its PSA 10 population across our whole measurement window: 386, then 386.

Not one new gem.

Shining Noctowl from Neo Destiny ran the same ladder, $2,600 to $3,000 prints in early May, then $4,200 to $6,400 since mid-June. And the move reaches well below trophy prices. Jessie & James from Hidden Fates is a $300 slab, one of the most liquid gems in the hobby, up 53% in 30 days on 106 sales. Its population grew by 127 copies on a base of nearly 16,000. Less than 1% new supply, and the bid ran anyway.

The trophy end has been telling the same story for weeks: a PSA 10 Umbreon Gold Star hammered at $168,000 on our June 29 board, the Espeon went for $90,000 the same week, and Monday we covered a $682,500 Rayquaza.

What's actually being priced

A new set's PSA 10 is a claim on a population that grows every week. Submissions keep flowing, modern print quality gems at a high rate, and every returned order lands supply directly at the top grade. A 2005 Gold Star's population is finished; the copies that will ever gem already have. Buyers are pricing that difference, and the eighteen-day pop numbers above are the cleanest look at it we've had.

Two names on the board don't fit, and we'd rather show you the exceptions than hide them. Kingdra ex, the promo, is down 55% in 30 days on a population that barely moved; that looks like plain demand fade on a card everyone already has. And Pikachu & Zekrom GX from Team Up shed a third of its price in June even as Team Up sealed climbed 28% on the month. Old doesn't automatically mean bid. The pattern holds where supply is still compounding, and it protects nothing else.

The outlook

The gem premium on a new set is a launch-window effect. It exists while slabs are scarce, those first few weeks when the population is tiny, and it erodes on schedule as the grading queue empties out. Whoever sold Mega Greninja gems on June 28 got $1,399. Two weeks of supply later, the same slab is an $850 card.

It's also why we're extremely careful buying anything still in print. While the printer runs, supply keeps arriving at every grade, and the same asset can put up the fastest gains on the board one month and the fastest drops the next. Eight of the ten biggest graded losers this month come from sets still sitting on shelves.

Pitch Black lands Friday. Figure roughly a month before its first gems come back from the graders, and the window opens again. We've now watched this cycle run twice in a row.

When those first Pitch Black gems hit the market, which side of the window are you on?
