Why Pokémon Base Set Cards Are Still Worth Big Money in 2026
Released in 1999, the Pokémon Trading Card Game Base Set is the holy grail for collectors worldwide. With only 102 cards in the set, it might seem modest — but the demand for high-grade copies of key cards has never been stronger. Whether you’re a seasoned collector or just found a dusty binder in the loft, here’s what you need to know about the most valuable Pokémon Base Set cards in 2026.
The Top 10 Most Valuable Pokémon Base Set Cards
1. Charizard #4 – Holo Rare
The king of Pokémon cards. A PSA 10 Shadowless Charizard has sold for over £300,000 at auction. Even a well-played Unlimited Charizard in good condition can fetch £100–£500 depending on condition. It’s the card every collector wants and the one that started the modern Pokémon card boom.
- PSA 10 (Shadowless): £200,000+
- PSA 9 (Unlimited): £800–£2,000
- Ungraded (Good condition): £100–£400
2. Blastoise #2 – Holo Rare
The Water-type starter’s final evolution is one of the most iconic cards in the set. Blastoise commands serious money in high grades, particularly Shadowless copies. Browse our Pokémon singles to see what’s currently in stock.
- PSA 10 (Shadowless): £15,000–£30,000
- PSA 9 (Unlimited): £300–£600
- Ungraded (Good condition): £30–£100
3. Venusaur #15 – Holo Rare
The Grass-type starter completes the trio. Venusaur is often undervalued compared to Charizard and Blastoise, making it a smart buy for collectors looking for long-term value.
- PSA 10 (Shadowless): £10,000–£20,000
- PSA 9 (Unlimited): £200–£400
- Ungraded (Good condition): £20–£80
4. Chansey #3 – Holo Rare
Often overlooked, Chansey is one of the rarer pulls from Base Set packs and holds strong value in high grades. A PSA 10 Shadowless Chansey is genuinely hard to find.
- PSA 10 (Shadowless): £5,000–£12,000
- Ungraded (Good condition): £15–£50
5. Ninetales #12 – Holo Rare
A fan favourite with stunning artwork, Ninetales is one of the most aesthetically pleasing cards in the set. High-grade copies are increasingly sought after.
- PSA 10 (Shadowless): £4,000–£8,000
- Ungraded (Good condition): £10–£40
6. Mewtwo #10 – Holo Rare
The most powerful Pokémon in the original lore, Mewtwo’s Base Set holo is a must-have for any serious collection. Demand remains consistently high.

- Ungraded (Good condition): £15–£60
7. Gyarados #6 – Holo Rare
The Sea Monster Pokémon has one of the most dramatic artworks in the set. Gyarados is a solid mid-tier holo that’s always in demand.
- PSA 10 (Shadowless): £3,000–£6,000
- Ungraded (Good condition): £10–£35
8. Raichu #14 – Holo Rare
Pikachu’s evolved form is one of the most recognisable Pokémon in the franchise. Raichu holos in top condition are a staple of any Base Set collection.

- Ungraded (Good condition): £10–£30
9. Alakazam #1 – Holo Rare
The Psychic-type powerhouse leads the Base Set numbering at #1. Alakazam is a collector’s favourite and holds strong value across all grades.

- Ungraded (Good condition): £10–£30
10. Clefairy #5 – Holo Rare
Originally intended to be the mascot of the Pokémon franchise before Pikachu took the crown, Clefairy holds a special place in Pokémon history. High-grade copies are surprisingly valuable.
- PSA 10 (Shadowless): £3,000–£6,000
- Ungraded (Good condition): £8–£25
Shadowless vs Unlimited — What’s the Difference?
You’ll notice “Shadowless” mentioned throughout this guide. Here’s what it means:
- Shadowless cards were printed in the very first print run of Base Set. They have no drop shadow on the right side of the artwork box, making them rarer and significantly more valuable.
- Unlimited cards are the more common print run with the shadow. Still valuable in high grades, but worth considerably less than Shadowless equivalents.
- 1st Edition cards have a small “1st Edition” stamp on the left side of the artwork. These are the rarest and most valuable of all.
Should You Get Your Cards Graded?
If you have Base Set holos in excellent condition, grading through PSA or CGC can significantly increase their value and saleability. A card that grades PSA 9 or PSA 10 can be worth 5–10x more than an ungraded equivalent. It’s worth the investment for key holos like Charizard, Blastoise and Venusaur.
