TL;DR
Iono SAR (350/190) from Shiny Treasure ex costs ¥24,800 to ¥27,600 in a PSA 10 slab today, PSA 9s are ¥8,000–¥8,888, and raw copies run ¥5,555 (wear noted) to ¥9,980 (shop stock). The cheapest slab is 4.5× the cheapest raw, and the PSA 9 is 32% of the 10 — the shiny-treasure Iono is a gem-mint-or-nothing card.
- Cheapest PSA 10: ¥24,800 (US$171.12) on Yahoo! Flea Market; ¥25,080 on Mercari, then ¥26,800–¥27,600.
- PSA 9s at ¥8,000 and ¥8,888 — under a third of a 10.
- Raw copies: ¥5,555 and ¥5,599 with slight wear, ¥9,980 clean from Suruga-ya.
- Twenty-one PSA 10s, four PSA 9s and thirty-one raws in stock.
As of September 2026, the Shiny Treasure ex Iono special art rare is the trainer card where the grade line is a cliff: ¥24,800 for a 10, ¥8,000 for a 9, and clean raws that cost more than the 9.
Here is a same-day read of Iono SAR 350/190 across PSA 10, PSA 9 and raw on Japanese marketplaces, why a 9 is worth so little, and the steps to buy from Japan.

Every price in this table is the seller’s listed price for that Iono copy, read from the item page on 2026-09-20; the USD figure is the checkout conversion shown alongside it. All rows are Japanese-language prints of the Pokémon TCG[5], and condition notes are the seller’s own Mercari / Yahoo! Flea Market condition field, translated — Suruga-ya rows are shop stock without one. Seller titles are in Japanese; the tiles further down link to each listing. Mercari itself permits overseas purchases through partner proxy services[3].
Yahoo! Flea Market has the floor at ¥24,800, Mercari at ¥25,080, then Yahoo! Flea Market at ¥26,800 and ¥27,000 and Mercari at ¥27,600 — a ¥2,800 spread, tight for a card at this level. None of the five offers authentication, which does not matter for a slab. The PSA 9s at ¥8,000 and ¥8,888 are both priced below a clean raw. Raw copies are ¥5,555 and ¥5,599 with slight-wear notes and authentication available, and ¥9,980 for Suruga-ya’s clean shop copy.

One scope note: this page prices the Japanese Iono 350/190 from Shiny Treasure ex high-class pack only. English prints of the same artwork have their own collector number, set name and market, and none of the figures here apply to them[5]. Promos and full-art variants from other sets are separate cards as well — check the number on the PSA label against 350/190 before comparing.
Is Iono PSA 10 worth 4.46× the raw card?
A 4.5× multiple against the worn raw, 2.5× against the clean one, and a PSA 9 at 32% of the 10: the market values a gem-mint Iono at ¥24,800 and everything else as a raw with or without a certificate. That is the signature of a card that grades hard — trainer SARs with white borders show every edge nick under PSA’s GEM MT 10 standard[6]. A self-submission on the ¥9,980 clean raw most often produces a ¥8,000 card. If you want the 10, buy the ¥24,800 slab; if you want a sealed Iono at a third of the price, the ¥8,000 PSA 9 is cheaper than the clean raw and the sensible buy.
| Route | Cost today (JPY, before shipping) | What you get |
|---|---|---|
| Buy the cheapest PSA 10 slab | ¥24,800 | Grade already locked in; you pay the full premium, nothing to wait for. |
| Buy the cheapest raw copy as-is | ¥5,555 | Cheapest way to own the artwork; condition is whatever the photos show. |
| Buy the cheapest raw copy with Mercari authentication | ¥7,255 | ¥5,555 + ¥1,700 authentication fee[1]; the card is checked for authenticity before it ships, but it is still ungraded. |
Buy the ¥24,800 Yahoo! Flea Market slab for the grade. Buy the ¥8,000 PSA 9 for a sealed copy — it undercuts the clean raw by ¥1,980. Skip the worn raws; with Mercari authentication[1] the ¥5,555 copy is ¥7,255 and still worn.
How to order Iono SAR 350/190 from a Japanese seller
A Yahoo! Flea Market slab goes through a proxy like any Mercari listing. The sequence:
- Step 1 — Open the listing on OneMall. Every tile below links straight to the OneMall item page for that exact copy, so you skip the Japanese-only Mercari app entirely.
- Step 2 — Check the slab label in the photos. Read the collector number on the PSA label before you pay; the same Pokémon often exists at several numbers in the same set.
- Step 3 — Add authentication if the seller offers it. For raw cards on Mercari, tick Mercari authentication at checkout (+¥1,700)[1][2]; the card is inspected before it leaves Japan.
- Step 4 — Pay the first invoice. Item price plus the service fee (as low as ¥200 per order) — international shipping is a separate second payment once the card is weighed at the warehouse.
- Step 5 — Consolidate and ship. Cards sit in free storage for 90 days, the first six orders consolidate free, and one padded parcel to the US goes out by ECMS or DHL.

Frequently Asked Questions
How much is a PSA 10 Iono SAR 350/190?
In-stock Japanese listings on 2026-09-20 price it at ¥24,800 to ¥27,600 (about US$171–190 before shipping); the cheapest is a Yahoo! Flea Market slab.
Why is the PSA 9 cheaper than a clean raw?
Buyers of this card want the 10; a 9 is treated as a certified raw. At ¥8,000 the PSA 9 undercuts Suruga-ya’s ¥9,980 clean raw copy.
Is it worth grading a raw Iono SAR myself?
Only as a gamble. Trainer SARs with white borders grade hard; a ¥9,980 clean raw most often becomes an ¥8,000 PSA 9, with the ¥24,800 outcome the exception.
How does 350/190 differ from Iono 096/071?
350/190 is the Shiny Treasure ex (sv4a) version; 096/071 is the Clay Burst (sv2d) original. Different sets, different numbers, different prices — match the number on the slab label.
How many PSA 10 Iono 350/190 exist?
The authoritative count is PSA’s own Population Report[6], which updates as submissions clear; this page deliberately does not copy a number that will drift. The live-supply proxy on 2026-09-20: 21 PSA 10 slabs in stock across Mercari, Yahoo! Flea Market and Suruga-ya, against 4 PSA 9 and 31 raw copies. A card with far more slabs than raws in stock has been graded heavily.
