A note on sourcing: the Iono’s Kilowattrel 104/100 prices above are the asking prices on each item page as of 2026-11-05, and USD is the conversion the page displayed at checkout. All copies are the Japanese print of the Pokémon TCG[5]. Condition notes come from the seller’s own Mercari / Yahoo! Flea Market condition field (translated); Suruga-ya rows are shop stock and carry none. Listing titles are in Japanese — the tiles below link to each copy. Mercari supports overseas buyers via partner proxy services[3].
The ¥6,000 Yahoo! Flea Market slab, noted “Almost Unused”, sets the floor on 2026-11-05; a second Yahoo! Flea Market slab noted “Unused” is ¥200 higher at ¥6,200, and the ¥6,999 Mercari slab, noted “No obvious damage or stains”, is ¥999 higher. Mercari official authentication (OneMall submits the item; Mercari official issues the conclusion; OneMall does not guarantee authenticity) is seller-enabled on Mercari listings only, and on a slab it is a nice-to-have rather than a need. Raw copies are cheap: a Mercari copy noted “Pre-owned” at ¥370 is the cheapest, with Suruga-ya shop stock at ¥480 and a Mercari unused copy at ¥690 behind it. Kilowattrel is not a chase card — it is Iono’s supporting Pokémon in the set’s partner-art series — so the raw floor tracks pack value.

Everything on this page refers to the Japanese-language Iono’s Kilowattrel, collector number 104/100 in Battle Partners. An English print of the same artwork is a different card with its own number, set name and market[5], as are promo versions and full-art variants from other sets. Match the number on the slab label before you compare any price.
Iono’s Kilowattrel PSA 10 value: is the slab worth 16.22× a raw copy?
A 16.22× multiple, or a ¥5,630 gap, between the cheapest raw and the cheapest slab is the grading premium on a card that costs less than a coffee ungraded (live listings, 2026-11-05). That premium is not about Kilowattrel; it is the cost of a PSA submission plus the chance the card comes back a 9, priced in. On a card with no PSA 9 in stock in either the 2026-09-29 sweep or the 2026-11-05 re-check, the downside of a 9 is stark — there is no established price for one, so a 9 would sell for barely more than raw. PSA’s GEM MT 10 standard[6] is unforgiving on centering, and Battle Partners art rares show enough print variance that not every pack-fresh copy makes it. That is why buying a finished 10 at ¥6,000 can make more sense than submitting a ¥370 raw and hoping.
| Route | Cost on 2026-11-05 (JPY, before shipping) | What you get |
|---|---|---|
| Buy the cheapest PSA 10 slab | ¥6,000 | Grade already locked in; you pay the full premium, nothing to wait for. |
| Buy the cheapest raw copy as-is | ¥370 | Lowest-cost route on this page’s data; condition is whatever the photos show. |
| Buy a raw copy that offers Mercari official authentication (OneMall submits the item; Mercari official issues the conclusion; OneMall does not guarantee authenticity) | raw price + ¥1,700 | Mercari official issues its conclusion before the card ships (OneMall does not guarantee authenticity)[1], but it is still ungraded. The option is seller-enabled on Mercari listings only — check the item page before you order. |
Buy the ¥6,000 Yahoo! Flea Market slab if you want the grade — on 2026-11-05 it is ¥200 below the ¥6,200 Yahoo! Flea Market slab and ¥999 below the ¥6,999 Mercari PSA 10 linked here. If the ¥690 Mercari raw’s item page shows the authentication option[1], it comes to ¥2,390 before fees and shipping for a binder copy with Mercari official’s conclusion (OneMall does not guarantee authenticity). The ¥370 Mercari copy is the budget route.
How to order Iono’s Kilowattrel AR 104/100 from a Japanese seller
Yahoo! Flea Market and Mercari listings are bought the same way through a proxy. Here is the sequence for this card.
- Step 1 — Pick the copy, not the average. Use the table above: the cheapest in-stock PSA 10 on 2026-11-05 is ¥6,000, ¥5,630 above the ¥370 raw; anything above the range there is paying for a seller’s optimism.
- Step 2 — Order through OneMall. Click the tile, add to cart, and a Japan-side team places the Mercari or Yahoo! Flea Market order for you — sellers who write 海外発送不可 (no overseas shipping) still ship because the address is a Tokyo warehouse.
- Step 3 — Optional Mercari official authentication (OneMall submits the item; Mercari official issues the conclusion; OneMall does not guarantee authenticity). Raw copies that show the authentication option can be checked for +¥1,700[1][2]; for a PSA slab the label already does that job.
- Step 4 — First payment, then wait for arrival photos. Ask for unboxing photos if you want to see the slab corners before it flies.
- Step 5 — Second payment for international shipping. A single slab is light; batch it with other cards while it sits in 90 days of free storage after arrival (30 days after consolidation) — the first six orders consolidate free — and pay one shipping fee.

Frequently Asked Questions
How much is a PSA 10 Iono’s Kilowattrel AR?
¥6,000 (US$41.40) and ¥6,200 (US$42.78) on Yahoo! Flea Market and ¥6,999 (US$48.29) on Mercari, the three live PSA 10 listings re-checked 2026-11-05.
Why are there no PSA 9 copies?
With raw copies at ¥370–¥690 (2026-11-05), a PSA 9 would be worth little more than the grading fee, so sellers who receive a 9 may not list it. The 2026-09-29 sweep found thirteen 10s and zero 9s.
Is a Yahoo! Flea Market slab as safe as a Mercari one?
The PSA holder and cert number are the assurance in both cases. The difference is that Mercari listings can add Mercari official authentication (+¥1,700) (OneMall submits the item; Mercari official issues the conclusion; OneMall does not guarantee authenticity)[1]; Yahoo! Flea Market listings cannot, but for a sealed slab that option adds little.
Can I get Iono’s Kilowattrel shipped to the US or Europe?
Yes. A proxy such as OneMall buys it to a Japanese address and forwards it; to the US the lanes are ECMS, DHL and Japan Post EMS (DDP), with no sea mail, and a single slab fits in the smallest parcel tier.
Is there a PSA population report for Iono’s Kilowattrel AR 104/100?
Yes — PSA’s Population Report[6] lists the census for every graded card, including this one, and it is the number to check before you buy for scarcity. It is not reproduced here because it changes constantly. The in-stock picture in the 2026-09-29 sweep — 13 PSA 10, 0 PSA 9, 12 raw copies — is the market-side supply figure this page recorded.
