In late September 2026 the Shiny Treasure ex Iono special art rare was 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. By 2026-11-05 the cheapest PSA 10 in the listings below is ¥23,900 and the PSA 9 is ¥7,980.
Here is a read of the Iono SAR 350/190 listings re-checked on 2026-11-05 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 2026-11-05; 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].
On 2026-09-29 Yahoo! Flea Market had the floor at ¥24,800, with Mercari at ¥25,080 and three more slabs up to ¥27,600; the PSA 9s were ¥8,000 and ¥8,888, and Suruga-ya had a clean raw at ¥9,980. On 2026-11-05 the listings below are PSA 10s at ¥23,900 (Mercari, nearly unused, Mercari official authentication (OneMall submits the item; Mercari official issues the conclusion; OneMall does not guarantee authenticity) available), ¥24,980 (Yahoo! Flea Market, unused) and ¥26,000 (Mercari, nearly unused); a ¥7,980 Yahoo! Flea Market PSA 9 (“Almost Unused”); and raws at ¥4,990 (Mercari Shops, “Pre-owned”; Mercari official authentication is not offered on this listing) and ¥5,555 (Mercari, “Slight damage or stain”, Mercari official authentication (OneMall submits the item; Mercari official issues the conclusion; OneMall does not guarantee authenticity) available). The ¥4,300 Yahoo! Flea Market raw and the ¥8,000 Mercari PSA 9 listed here on 2026-10-30 and the ¥24,000 Yahoo! Flea Market PSA 10 from the 2026-11-03 check have sold.

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 4.79× the raw card?
A 4.79× multiple (a ¥18,910 gap) against the ¥4,990 raw, 4.30× against the ¥5,555 one, and a PSA 9 at 33% of the 10: the market values a gem-mint Iono at ¥23,900 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], and the ¥5,555 raw in the listings carries a wear note while the ¥4,990 copy is listed only as “Pre-owned”. If you want the 10, buy the ¥23,900 slab; if you want a sealed Iono at about a third of the price, the ¥7,980 PSA 9 is the sensible buy.
| Route | Cost today (JPY, before shipping) | What you get |
|---|---|---|
| Buy the cheapest PSA 10 slab | ¥23,900 | Grade already locked in; you pay the full premium, nothing to wait for. |
| Buy the cheapest raw copy as-is | ¥4,990 | Lowest-cost route on this page; condition is whatever the photos show. |
| Buy the cheapest raw copy with Mercari official authentication (OneMall submits the item; Mercari official issues the conclusion; OneMall does not guarantee authenticity) | ¥7,255 | The ¥5,555 Mercari raw + ¥1,700 authentication fee[1] (the ¥4,990 Mercari Shops copy does not offer it); Mercari official issues its conclusion before the card ships (OneMall does not guarantee authenticity), but it is still ungraded. |
Buy the ¥23,900 Mercari slab for the grade. Buy the ¥7,980 PSA 9 for a sealed copy. The ¥4,990 Mercari Shops raw is listed only as “Pre-owned” and does not offer Mercari official authentication; with Mercari official authentication (OneMall submits the item; Mercari official issues the conclusion; OneMall does not guarantee authenticity)[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 official authentication (OneMall submits the item; Mercari official issues the conclusion; OneMall does not guarantee authenticity) 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 (¥300 per item on most marketplaces; from ¥200 per item on Yahoo Auctions and LinkBuy) — 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 after arrival (30 days after consolidation), the first six orders consolidate free, and one padded parcel to the US goes out by ECMS, DHL or Japan Post EMS (DDP).

Frequently Asked Questions
How much is a PSA 10 Iono SAR 350/190?
The PSA 10 slabs in the listings above ask ¥23,900 to ¥26,000 (about US$165–179 before shipping), checked 2026-11-05; the cheapest is a Mercari slab, the next a Yahoo! Flea Market slab at ¥24,980, and the third another Mercari slab. On 2026-09-29 in-stock listings ran ¥24,800 to ¥27,600.
How does the PSA 9 compare with a raw copy?
Buyers of this card want the 10; a 9 is treated as a certified raw. On 2026-11-05 the ¥7,980 PSA 9 is 33% of the cheapest PSA 10 and ¥2,990 above the ¥4,990 cheapest raw; in the 2026-09-29 sweep a ¥8,000 PSA 9 undercut 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; the raw copies in the listings checked on 2026-11-05 are ¥4,990 (“Pre-owned”) and ¥5,555 (wear noted), and a PSA 9 lists at ¥7,980 against ¥23,900 for a 10.
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 in the 2026-09-29 sweep: 21 PSA 10 slabs in stock across Mercari, Yahoo! Flea Market and Suruga-ya, against 4 PSA 9 and 31 raw copies. Raws still outnumbered slabs in that sweep, but 21 slabs in stock shows the card has been submitted for grading in volume.
