Mega Gengar ex SAR: What a PSA 10 Actually Sells For
377 graded sales on record, a live average, and the four copies you can buy today — with the gap between the headline average and this week’s real prices spelled out.
377 PSA 10 sales
TL;DR — the short answer
A PSA 10 Mega Gengar ex SAR (240/193) has averaged ¥108,621 across 377 recorded sales, but the last eleven sales all landed between ¥79,500 and ¥96,614 — the card is trading roughly 15–20% below its lifetime average. A PSA 9 averages ¥60,696, so gem mint carries about a 1.8× premium.
- Buy the recent number, not the average. The lifetime average is inflated by launch-week prices.
- PSA 10 population is not tiny. 377 recorded sales means supply keeps arriving — there is no rush premium worth paying.
- Verify the cert before you pay. Listings that state 240/193 and show the label are the ones worth bidding on.

What it sells for, by grade
Every figure below comes from recorded Japanese marketplace sales of this exact card — Mega Gengar ex SAR, collector number 240/193, from the M2a MEGA Dream ex high-class pack.[1]
| Grade | Sales on record | Average | Low | High |
|---|---|---|---|---|
| PSA 10 | 377 | ¥108,621 | ¥5,980 | ¥165,250 |
| PSA 9 | 18 | ¥60,696 | ¥49,999 | ¥74,000 |
| PSA 8 | 4 | ¥44,542 | ¥42,000 | ¥49,500 |
Read the low column carefully. That ¥5,980 PSA 10 is an outlier, not a bargain you can repeat — almost certainly a mispriced or bundled listing. The honest floor for a gem mint copy is the mid-¥70,000s.
Why the average overstates today’s price
The lifetime average includes the launch window, when the card first came out of MEGA Dream ex packs and buyers paid whatever was asked. Here is what actually changed hands in the first week of August 2026:
| Slab | Sold | Price | Grade |
|---|---|---|---|
 |
2026-08-06 | ¥79,500 | ARS 10 |
 |
2026-08-06 | ¥87,000 | PSA 10 |
 |
2026-08-06 | ¥86,999 | PSA 10 |
 |
2026-08-05 | ¥85,500 | PSA 10 |
 |
2026-08-04 | ¥88,000 | PSA 10 |
 |
2026-08-03 | ¥96,614 | PSA 10 |
 |
2026-08-03 | ¥90,000 | PSA 10 |
 |
2026-08-02 | ¥95,555 | PSA 10 |
 |
2026-08-02 | ¥94,400 | PSA 10 |
 |
2026-08-01 | ¥92,494 | PSA 10 |
 |
2026-08-01 | ¥91,500 | PSA 10 |
Eleven sales, median around ¥90,000, none above ¥96,614. Against a lifetime average of ¥108,621, this week’s buyer is paying about 17% less than the headline number suggests. If a seller quotes you “the average price”, that is the gap they are quoting from.
Is the gem mint premium worth it?
| Comparison | Average price | Multiple vs PSA 9 | Liquidity |
|---|---|---|---|
| PSA 10 | ¥108,621 | 1.79× | 377 sales — sells any week |
| PSA 9 | ¥60,696 | 1.00× | 18 sales — thin, slower exit |
| PSA 8 | ¥44,542 | 0.73× | 4 sales — very thin |
On this card the gem mint premium is 1.79× — modest by grail standards, where 5× and up is common. That is what a 377-copy PSA 10 population does to scarcity pricing.
The practical consequence: PSA 9 is the value play here and PSA 10 is the liquidity play. If you want the card on a shelf, a PSA 9 at roughly ¥51,000–74,000 gets you the same artwork for half the money. If you want to be able to sell it quickly, the PSA 10 market is twenty times deeper.

Match the collector number
This card is 240/193 from M2a. A listing that only says “Mega Gengar ex SAR” without the number may be a different print from the same set.
-
Read the grader, not just the number
“10” on the label can mean PSA 10, ARS 10 or another house. ARS copies trade lower — the ¥79,500 sale above was an ARS 10, the cheapest of the eleven for exactly that reason.
-
Verify the cert
PSA publishes every certificate number; type it into their lookup and confirm the card, set and grade match the photos before you commit.[2]
-
Check the slab photo, not the stock image
You want a photo of the actual case, front and back, with the label readable. No readable label, no bid.
Buy it from Japan, delivered to your door
OneMall buys the card on Mercari for you, checks it in at the Japanese warehouse, and ships it on. Flat ¥300 proxy fee per order, 90 days of free storage while you consolidate.
Frequently asked questions
How much is a Mega Gengar ex SAR PSA 10 worth in 2026?
Across 377 recorded sales the average is ¥108,621, but sales in the first week of August 2026 ran ¥85,500–96,614. Budget around ¥90,000 for a clean PSA 10 today; the higher lifetime average reflects launch-window prices that are no longer being paid.
What is the card number for Mega Gengar ex SAR?
240/193, from the Japanese M2a set (MEGA Dream ex high-class pack). The number above the set total is what marks it as a Special Art Rare pulled beyond the base numbering.
Is a PSA 9 worth buying instead?
On this card, yes, if you are buying to keep it. PSA 9 averages ¥60,696 — roughly 56% of gem mint money for the same artwork. The trade-off is liquidity: 18 PSA 9 sales are on record against 377 PSA 10s, so reselling takes longer.
Why do some listings say ARS 10 instead of PSA 10?
ARS is a separate Japanese grading company. An ARS 10 is not interchangeable with a PSA 10 and sells for less — the ¥79,500 sale on 6 August was an ARS 10, the cheapest of the recent eleven. If you are buying for resale outside Japan, PSA carries the wider recognition.
Can I buy this card from outside Japan?
Most of these listings are individual Mercari Japan sellers who do not ship internationally. A proxy service buys on your behalf at a Japanese address and forwards the package — that is what the listings above link to.
