Mega Gengar ex 240/193: a listing-check checklist

If you are looking at Japanese Mega Gengar ex listings, the character name is the least useful part of the title. The safer way to compare copies is to start with the collector number: 240/193. That number points to the Special Art Rare from the Japanese MEGA Dream ex high-class pack and separates it from other Mega Gengar ex cards, promos, and international prints.

Here is the checklist I would use before saving a listing or placing an order.

1. Match the number before the artwork

Search for "240/193" together with ゲンガー or PSA10. Japanese sellers often use short titles, and translated names can vary. The collector number is the most dependable first filter. A similar illustration or the words "Mega Gengar" alone do not prove that two listings are the same card.

2. Read the PSA label, not just the seller title

For a graded card, zoom in on the slab label and confirm the set, year, language, collector number, and grade. Then check that the certification number in the photos matches the number stated in the listing. A photo of a slab is useful evidence, but it is still worth comparing every field rather than relying on "PSA 10" in the title.

3. Treat raw and graded copies as different buying decisions

A PSA 10 listing gives you a third-party grade in a sealed holder. A raw copy can cost less, but photos and seller condition notes carry much more weight. Look for clear front, back, corner, and edge images. Whitening, print lines, centering, dents, and surface scratches may not appear in a single overhead photo.

For raw cards, Japanese condition labels are a starting point, not a substitute for close inspection. "No obvious damage or stains" describes the seller's selected condition field; it is not a grading promise.

4. Separate card condition from holder condition

A graded card can have a scratched, chipped, or scuffed slab even when the card received a high grade. If the seller mentions case wear, decide whether you are buying it for display, storage, or resale. For a display copy, reflections across the holder can hide scratches, so angled photos are especially helpful.

5. Compare marketplace features as well as asking prices

Two copies with the same grade can differ because of seller reputation, photo quality, stated condition, return rules, or optional marketplace services. Asking prices are not completed-sale data, and an unusually low listing deserves more inspection rather than an automatic assumption that it is the best value.

Some eligible Mercari trading-card listings offer Mercari official authentication for a fee. OneMall can submit an eligible item, and Mercari official issues the conclusion; OneMall does not independently guarantee authenticity. Yahoo! Flea Market listings may not offer the same option, so a cross-platform price gap is not necessarily an apples-to-apples comparison.

6. Save evidence before international shipping

Keep screenshots of the listing title, photos, seller notes, collector number, and certification number. If you use a proxy service, consider ordering unboxing photos or a wrong/missing-item check before the parcel leaves Japan. Those services cannot grade a card or guarantee authenticity, but they can help confirm that the received item matches the order and document its visible condition.

For a fuller breakdown of this exact Japanese card, including how the raw, PSA 9, and PSA 10 listings were separated at the time of the original survey, see the Mega Gengar ex 240/193 Japan listing guide. Prices and inventory change, so use its dated figures as a snapshot and repeat the listing checks above before buying.

The short version: number first, label second, condition third, price fourth. That order prevents most of the expensive mistakes that happen when several cards share the same character and similar artwork.

The 380-HP Pokemon card ceiling, and why HP does not set the price

The highest printed HP on a Pokemon card is now 380, but the more interesting collector lesson is that HP and market price barely move together.

Three Pokemon share the 380-HP ceiling: Mega Venusaur ex, Mega Emboar ex, and Wailord ex. Mega Venusaur ex was the first to reach it in September 2025. Mega Emboar ex matched it in January 2026, and Wailord ex joined the group in July 2026. Before that, 340 HP had been the ceiling since Snorlax VMAX arrived in February 2020.

That is a large mechanical jump, but it does not create a simple price ladder. The character, artwork, rarity, condition, and grade matter much more than the number in the upper-right corner. In Japanese listings checked for the source guide in September, a PSA 10 Mega Venusaur ex SAR at 380 HP was listed far below a PSA 10 Mega Charizard X ex SAR at 360 HP. Charizard demand outweighed the twenty-point HP difference.

Here is the current upper tier by Pokemon rather than by every rarity variant:

380 HP: Mega Venusaur ex, Mega Emboar ex, Wailord ex

370 HP: Mega Dragonite ex, Mega Feraligatr ex

360 HP: Mega Gardevoir ex, Mega Charizard X ex, Mega Meganium ex, Mega Charizard Y ex

350 HP: Mega Abomasnow ex, Mega Gengar ex, Mega Eelektross ex, Mega Greninja ex, Mega Gallade ex, Mega Delphox ex, Mega Chandelure ex

340 HP: Snorlax VMAX, Eternatus VMAX, Copperajah VMAX, Skeledirge ex, Palafin ex, Tyranitar ex, Venusaur ex, Torterra ex, Garganacl ex, Slaking ex, Mamoswine ex, Steven's Metagross ex, Mega Camerupt ex, Mega Lucario ex, Mega Pyroar ex, and Mega Excadrill ex

Wailord is the oddest member of the 380 group. The two Mega Evolution Pokemon ex give up three Prize cards when knocked out. Wailord ex is a Stage 1 Pokemon ex that gives up two, balanced in part by a Retreat Cost of four and an attack that leaves it Asleep. Wailord also has the highest HP on an ordinary single-Prize Pokemon: 240 HP in Journey Together.

For collectors comparing Japanese and English versions, the HP is the same for the same card. The language, set name, and collector number can differ, but the gameplay statistic does not. That makes the collector number a safer identifier than the Pokemon name alone. A search for "Mega Venusaur ex" can mix Double Rare and Special Art Rare cards, different numbers, raw copies, and graded slabs.

The same caution applies to population and condition. A high-HP card is not automatically scarce. A PSA 10 price should not be compared directly with a raw asking price, and an asking price is not the same thing as a completed sale. When checking a Japanese listing, I would record the exact collector number, rarity, language, grade, certification number, seller photos, and whether the price comes from an active listing or a sold result.

The full source guide has the dated Japanese price snapshot, release timeline, and every Pokemon at 340 HP or above: Highest HP Pokemon Card: the complete 340-380 HP list. It is a commercial source from OneMall and is linked here because it contains the complete tables behind this summary.

OneMall does not independently authenticate listings or guarantee item condition. For graded cards, verify the slab and certification details yourself; for raw cards, examine the listing photos and description carefully. Mercari authentication is optional only on eligible listings, and any conclusion comes from Mercari rather than OneMall.

Disclosure: I help maintain the OneMall source guide. This post is a condensed, discussion-focused rewrite rather than a copy of the original article.

For collectors here, which is more surprising: that the ceiling stayed at 340 for five and a half years, or that the 380-HP record holder can cost less than a lower-HP Charizard?
