Iono’s Kilowattrel AR 104/100
The gem mint copy runs about 1.9× the raw one, which is the whole question this page answers: pay up for the slab, or take the centering risk yourself. The PSA 9 sample is thin (2 sales), which tells you most submissions of this card either come back a 10 or never get listed. Every number below comes from 132 recorded PSA 10 sales, with a working median of ¥7,500.
132 PSA 10 sales
TL;DR — the short answer

Median of the first half of that window: ¥6,999. Median of the second half: ¥7,500 — a 7% move up across 20 recorded gem mint sales. (Comparing halves rather than single days keeps one thin trading day from distorting the picture.)
Why it ran up in the first place
Art Rares are numbered above the set total like the Special Art Rares above them, but they come out of packs far more often, so the scarcity here is about condition rather than about supply. That is why the graded premium, not the card itself, carries the price — and why the early market still overshoots — the ¥8,000 high sitting in this card’s sales record is what that overshoot looked like. What has happened since is supply catching up as more copies get opened, graded and listed.
What the data suggests next
- Supply: 132 PSA 10 sales are on record. That is a card being graded in volume, not a scarcity story.
- Liquidity: 20 gem mint sales across the 25 days from 2026-07-21 to 2026-08-14 — roughly 0.8 a day, so there is a live two-sided market to price against.
- The raw shelf: ungraded copies are clustered tightly around ¥3,980, which anchors the bottom of the range.
Is it worth submitting a raw copy?
| Step up | Price move | Multiple | Liquidity |
|---|---|---|---|
| Raw → PSA 10 | ¥3,980 → ¥7,483 | 1.9× | 132 sales on record |
| PSA 9 → PSA 10 | ¥2,620 → ¥7,483 | 2.86× | 2 PSA 9 sales |
The arithmetic that matters: a raw copy costs about ¥3,980. Graded a 10 it is worth roughly ¥7,483, graded a 9 about ¥2,620. Add grading fees and international shipping both ways, plus the wait.
So the decision is not “is a PSA 10 worth it” — the market has already answered that at 1.9×. It is how confident you are that this particular copy grades a 10, because a 9 returns roughly ¥2,620 and wipes out the margin. Centering is what usually decides it, and you can judge that from the listing photos before you buy.

Match the collector number
This card is 104/100 from sv9. Sets often contain a cheaper regular-art version of the same card, and search results mix them constantly. No number in the listing, ask before bidding.
-
Judge centering from the photos
On a raw copy this is the single thing that decides a 10 versus a 9. Compare the border widths on all four sides; anything visibly off-centre is a 9 at best.
-
Verify the cert if it is slabbed
PSA publishes every certificate number. Enter it in their lookup and confirm the card, set and grade match the photos before you commit.[2]
-
Use the authentication option
Every listing above supports Mercari’s inspection service. On a card where a genuine copy runs into five figures, having the platform confirm it before shipping is worth the extra step.
Buy it from Japan, delivered to your door
OneMall buys the card on Mercari for you, checks it in at the Japanese warehouse and ships it on. Flat ¥300 proxy fee per order, 90 days of free storage while you consolidate.
Frequently asked questions
How much is a PSA 10 Iono’s Kilowattrel AR worth?
Across 132 recorded sales the average is ¥7,483, and the most recent 12 sales have a median of ¥7,500. Use the median — the lifetime average includes the launch window, when prices ran as high as ¥8,000.
What is the difference between a PSA 10 and an ungraded copy?
Physically nothing — a PSA 10 is an ordinary card that was submitted for grading and came back flawless. What you pay for is an independent verdict plus a sealed holder:
- Authenticity — PSA confirms the card is genuine and publishes the certificate number for anyone to check.
- Condition, judged not claimed — centering, corners, edges and surface measured against a fixed standard instead of a seller writing “mint”.
- A sealed case — the condition cannot change in transit or storage, which is why graded cards move across borders with far less friction.
- Price — here a PSA 10 averages ¥7,483 against about ¥3,980 for a raw copy: 1.9× for that verdict.
Submitting your own copy only pays if it comes back a 10; a 9 is worth about ¥2,620 here, and the fee and wait are gone either way.
What is the collector number for this card?
104/100, from sv9. The number above the set total marks it as an Art Rare, printed beyond the base numbering with full-card artwork — which is why it is worth more than the regular version of the same card.
Should I buy raw and grade it myself?
Only if you are confident in the centering. A raw copy costs about ¥3,980 and a PSA 10 is worth roughly ¥7,483, so the upside is real — but a PSA 9 returns about ¥2,620, which after fees and two international shipping legs leaves little or nothing. Buying a copy already in a 10 holder costs more and removes the risk entirely.
Can I buy this card from outside Japan?
Most of these are individual Mercari Japan sellers who do not ship internationally. A proxy service buys on your behalf at a Japanese address and forwards the parcel — that is what the listings above link to.
Is the authentication service worth using?
On a graded card, yes. Every listing in this article supports it: Mercari inspects the item and confirms it is genuine before it ships. Together with the certificate number on the PSA label — which anyone can verify at psacard.com/cert — that gives you two independent checks before the money crosses a border.
