Mewtwo GX SM-P 364 Promo PSA10: A Promo Collector's Guide

What the PSA10 slab actually confirms

A PSA10 label tells you the card was professionally graded and sealed by PSA in a tamper-evident holder. It does not guarantee the card will stay in that condition forever, and it does not tell you how the card was stored before grading. The grade reflects the card's condition at the time PSA evaluated it.

For the Mewtwo GX SM-P 364 promo, that distinction matters. You are buying a specific graded copy, not a generic mint card. The listing photos show the actual item, and each slab carries a unique PSA certification number that you can verify on the official PSA website before you pay.

The Mewtwo GX SM-P 364 slab in this listing

• Mewtwo GX: PROMO[SM-P 364](SM-P Promotional cards) - PSA10: Authentic PSA-graded Pokémon Trading Card, 100% genuine and officially licensed by The Pokémon Company / Nintendo. Confirms the card is an official product, not a counterfeit, which is the first checkpoint for any Japanese promo purchase.

  

• Mewtwo GX: PROMO[SM-P 364](SM-P Promotional cards) - PSA10: Professionally graded and sealed by PSA in a tamper-evident holder, grade PSA10 as shown in the title and photos. The PSA10 grade is the headline reason to pay a premium over a raw copy, but it only describes condition at grading time.
• Mewtwo GX: PROMO[SM-P 364](SM-P Promotional cards) - PSA10: Each slab carries a unique PSA certification number, verifiable on the official PSA website. Lets you independently confirm the grade and certification before committing, rather than relying on the listing alone.
• Mewtwo GX: PROMO[SM-P 364](SM-P Promotional cards) - PSA10: You will receive the exact graded card shown in the listing photos. Removes the guesswork of buying a representative image; you can inspect centering and surface in the photos first.

Why SM-P promotional cards sit in a different buying lane

SM-P promotional cards were distributed outside the main booster set structure, which means their supply story is different from a standard set card. The SM-P 364 checklist entry identifies this Mewtwo GX as part of that promotional numbering, and promo collectors often treat those numbers as their own mini-set to complete.

That changes how you should judge value. A PSA10 promo is not automatically rarer or more desirable than a PSA10 set card; it depends on how many copies were distributed and how many survived in gradeable condition. The supplied information does not include population figures or print-run data, so treat any rarity claim you see elsewhere as unverified unless it comes from PSA's own population report.

Graded PSA10 versus a raw copy: the real trade-off

The catalog price for this slab is USD 20,790.62, with a comparison price of USD 31,500.94. That gap is the practical starting point for your decision, not proof of market value.

• What the PSA10 slab gives you: Authentication, a tamper-evident holder, a verifiable certification number, and protection from handling damage. You also get the exact card shown, so you can assess centering before buying.
• What a raw copy gives you: Usually a lower entry price and the option to grade later yourself. The risk is that the raw card may not achieve a PSA10, and you absorb grading fees and turnaround time.
• The honest limitation: The supplied information does not include PSA population data, recent sale prices, or a condition report beyond the grade. Those gaps mean you should compare against other PSA10 listings and sold prices before treating the catalog price as a benchmark.

A checklist before you commit to this slab

1. Verify the certification number: Look up the unique PSA number on the official PSA website and confirm it matches the grade and card in the listing.
2. Inspect the holder in the photos: Check for cracks, scuffs, or label damage. The card is shipped in its sealed PSA case, but transit can still stress the holder.
3. Confirm what happens if the parcel arrives damaged: The seller asks buyers to inspect the parcel on arrival and contact them promptly with photos. Record a video while opening the package, as the returns guidance requests.
4. Check the return window and condition rules: Returns are accepted within 30 days of delivery, but the item must be in its original, sealed PSA holder and unaltered condition. If the item is not as described or the error is the seller's, they cover return shipping.
5. Plan for duties and taxes: Import duties, taxes, and VAT are the buyer's responsibility and are set by the destination country. For UK and EU orders, VAT may be collected at checkout or on delivery.

Shipping timelines and what they mean for your budget

Orders are dispatched within 1–3 business days after payment clears, with no dispatch on weekends or public holidays. Standard international delivery is estimated at 5–12 business days for the United States, UK, Australia, France, and Germany; 7–15 business days for Canada, the Netherlands, Spain, Italy, Sweden, Switzerland, and Ireland; 5–12 business days for the rest of Asia; and 10–20 business days for other regions.

Expedited shipping is available on request with a quote, so if you need the card for a specific date, ask before paying rather than assuming standard delivery will meet it. The card ships worldwide with full tracking and is insured in transit, which matters for a high-value slab.

How to decide whether this Mewtwo GX promo fits your collection

Buy this slab if you want a verified, encapsulated PSA10 promo without the grading process, and if the SM-P promotional numbering is a set you actively collect. The exact-card photos and verifiable certification make it a relatively low-ambiguity purchase for a high-value item.

Hold off if you are chasing the lowest entry price, if you want the option to grade a raw copy yourself, or if you need population data to judge relative rarity. The supplied listing does not include that data, and no buying guide should pretend otherwise. Use the certification check and the 30-day return window as your safety net, and confirm shipping and tax costs before you commit.
