The figures are listed prices, not sold prices: each was read from the live item page for that Mega Gengar ex copy on 2026-09-20, with USD as the item page’s own checkout conversion. Everything shown is the Japanese-language print of the Pokémon TCG[5]. Condition is the seller’s Mercari / Yahoo! Flea Market condition field, translated; Suruga-ya is shop stock with no condition field. Seller titles are Japanese, and the tiles further down open each listing. Mercari allows overseas purchases only through partner proxy services[3].
Yahoo! Flea Market has the three cheapest slabs at ¥65,000, ¥65,500 and ¥66,000; Mercari’s cheapest are ¥82,000 and ¥85,000 with authentication, and ¥88,000 with a slight-wear note on the holder. The ¥16,000 platform gap is real: Yahoo! Flea Market sellers cannot offer authentication and price for it. PSA 9s are ¥41,888 and ¥48,000 unused with authentication, and ¥62,000 with holder wear. Raw copies: ¥37,900 clean with authentication, ¥40,000 with slight wear, ¥40,280 clean from a shop, ¥54,800 for Suruga-ya’s stock. Seventeen raws in stock against fifty-four slabs.

Scope: Japanese Mega Gengar ex 240/193 (MEGA Dream ex high-class pack). The English-language print of this illustration has a different collector number and set name and is priced in a separate market, so the figures here do not transfer[5]. Promo copies and full-art variants from other sets are likewise different cards — the number on the PSA label is what to match.
Mega Gengar ex PSA 10 value: is the slab worth 1.72× a raw copy?
A 1.7× multiple, a ¥27,100 gap, and a PSA 9 at 64%: the market pays ¥3,988 for the certificate over a clean raw and ¥23,112 for the gem-mint label over a 9. A self-submission on the ¥37,900 clean raw with authentication gains little as a 9 and ¥27,100 as a 10 — fifty-four slabs say PSA’s GEM MT 10 standard[6] is met often on this dark card, though the ¥62,000 PSA 9 with holder wear is a reminder that slabs are not immune to handling. The ¥65,000 Yahoo! Flea Market slab is the buy; the ¥82,000 Mercari copy is the same card with authentication and a ¥17,000 platform premium.
| Route | Cost today (JPY, before shipping) | What you get |
|---|---|---|
| Buy the cheapest PSA 10 slab | ¥65,000 | Grade already locked in; you pay the full premium, nothing to wait for. |
| Buy the cheapest raw copy as-is | ¥37,900 | Cheapest way to own the artwork; condition is whatever the photos show. |
| Buy the cheapest raw copy with Mercari authentication | ¥39,600 | ¥37,900 + ¥1,700 authentication fee[1]; the card is checked for authenticity before it ships, but it is still ungraded. |
Buy the ¥65,000 Yahoo! Flea Market slab with unboxing photos and DHL. The ¥41,888 PSA 9 with Mercari authentication[1] (¥43,588 all-in) is the sealed alternative. The ¥37,900 clean raw with authentication (¥39,600 all-in) is the submission candidate.
How to buy Mega Gengar ex SAR 240/193 from Japan
A slab at this price earns the photo service, DHL, and a check of the cert number before the second payment. Here is the sequence.
- Step 1 — Search by collector number. On OneMall, searching “240/193 PSA10” in the Mercari tab surfaces slabs the English name never would — most Japanese sellers title the card in katakana.
- Step 2 — Compare against today’s floor. Today’s floor is ¥65,000 for a PSA 10 and ¥37,900 raw; treat those as your anchors when a new listing appears.
- Step 3 — Buy it. One click adds the item; the order is placed on Mercari on your behalf and received at the Japan warehouse.
- Step 4 — Authentication or inspection. Mercari authentication (+¥1,700) is available on listings that show it[1][2]; the proxy’s own inspection and photo service covers the rest.
- Step 5 — Ship when you are ready. Free storage runs 90 days, so several cards from different sellers can leave as one consolidated parcel.

Frequently Asked Questions
How much is a PSA 10 Mega Gengar ex SAR 240/193?
In-stock Japanese listings on 2026-09-20 price it at ¥65,000 to ¥88,000 (about US$449–607 before shipping); Yahoo! Flea Market slabs are ¥65,000–¥66,000, Mercari slabs ¥82,000–¥88,000.
Why is Mercari ¥16,000 more expensive than Yahoo! Flea Market for the same PSA 10?
Mercari sellers can offer authentication[1] and a larger buyer pool, and price for it; Yahoo! Flea Market sellers compete on price. For a PSA slab the authentication adds little, so the cheaper platform wins.
Is the PSA 9 Mega Gengar ex 240/193 good value?
At ¥41,888 the PSA 9 is 64% of the cheapest PSA 10, unused, sealed, with authentication available — a fair sealed option, though only ¥3,988 above a clean raw.
Which set is Mega Gengar ex SAR from?
The MEGA Dream ex high-class pack (M2a, MEGAドリームex); 240/193 is its special-art-rare number above the 193-card base, and it is the pack’s headline chase card.
Is there a PSA population report for Mega Gengar ex SAR 240/193?
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 — 54 PSA 10, 5 PSA 9, 17 raw copies — is the market-side supply figure this page can stand behind.
