TL;DR
Iono’s Kilowattrel AR (104/100) from Battle Partners costs ¥6,200 to ¥8,930 in a PSA 10 slab on Japanese marketplaces today, while raw copies sit at ¥680–¥837. No PSA 9 was in stock. The cheapest slab is 9.1× the cheapest raw, and Yahoo! Flea Market sellers undercut Mercari by several hundred yen.
- Cheapest PSA 10: ¥6,200 (US$42.78) on Yahoo! Flea Market; the only Mercari slab with authentication is ¥6,999.
- Raw copies: ¥680 from Suruga-ya shop stock, ¥700 on Mercari with authentication available.
- Thirteen PSA 10 slabs and no PSA 9 in stock — sellers are not slabbing 9s of this card.
- The ¥8,930 top listing is 44% above the floor for the same label; ignore it.
As of September 2026, Battle Partners’ trainer-themed art rares are cheap to slab and cheap to buy, and Iono’s Kilowattrel shows the pattern clearly: three Yahoo! Flea Market slabs at ¥6,790 or less and a Mercari market that starts ¥799 higher.

A note on sourcing: the Iono’s Kilowattrel 104/100 prices above are the asking prices on each item page as of 2026-09-20, 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 Yahoo! Flea Market trio — ¥6,200, ¥6,500 and ¥6,790 — sets the market. Mercari’s cheapest slab is ¥6,999 and it is the only one with Mercari authentication enabled, which is a nice-to-have on a slab rather than a need. The ¥8,930 Mercari copy carries no better condition note than the ¥6,200 one; it is simply priced high. Raw copies are stable: Suruga-ya’s shop stock at ¥680 is, unusually, the cheapest, with a Mercari unused copy at ¥700 that can be authenticated and a ¥837 used copy 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 9.12× a raw copy?
The ¥5,520 gap between the cheapest raw and the cheapest slab is the grading premium on a card that costs less than a coffee ungraded. 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 zero PSA 9 supply 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 ¥6,200 beats submitting a ¥700 raw and hoping.
| Route | Cost today (JPY, before shipping) | What you get |
|---|---|---|
| Buy the cheapest PSA 10 slab | ¥6,200 | Grade already locked in; you pay the full premium, nothing to wait for. |
| Buy the cheapest raw copy as-is | ¥680 | Cheapest way to own the artwork; condition is whatever the photos show. |
| Buy a raw copy that offers Mercari authentication | raw price + ¥1,700 | Authentication[1] is seller-enabled; the cheapest raw listing today does not offer it, so compare the next ones in the table above. |
Buy the ¥6,200 Yahoo! Flea Market slab if you want the grade — it is the cheapest gem mint on the market by ¥300. Buy the ¥700 Mercari raw with authentication[1] (¥2,400 all-in) if you want a checked-genuine binder copy and do not care about the holder. The ¥680 Suruga-ya copy is the pure 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 today is ¥6,200; 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 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 authentication. 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 inside the 90-day free storage window and pay one shipping fee.

Frequently Asked Questions
How much is a PSA 10 Iono’s Kilowattrel AR?
Between ¥6,200 and ¥8,930 on in-stock Japanese listings read 2026-09-20; the three cheapest are Yahoo! Flea Market slabs at ¥6,200, ¥6,500 and ¥6,790 (about US$43–47).
Why are there no PSA 9 copies?
With raw copies at ¥680–¥837, a PSA 9 would be worth little more than the grading fee, so sellers who receive a 9 tend not to list it. Today’s 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 authentication (+¥1,700)[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 and DHL, 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 on 2026-09-20 — 13 PSA 10, 0 PSA 9, 12 raw copies — is the market-side supply figure this page can stand behind.
