Rare Pokémon cards could be worth thousands - these are the ones to watch out for

Starting with the first video games – Red and Blue – which were released in 1996, the franchise has sprawled to include everything from a cartoon series, movies and of course a card game.

You may not have managed to catch ‘em all, but you could still have some valuable Pokémon cards hidden amongst your collection.

It’s over two decades since the earliest cards were released and still the most desirable Pokémon cards can fetch thousands of pounds.

A recent study from Progressive Money has revealed the three most desirable cards and they could fetch you a small fortune.

The top card, according to current valuations, is the Charizard card, released in the 2003 Skyridge Series of cards. On average, the card currently fetches a sum of £1,670.

The card is closely followed by the second highest earner in the collection, the Espeon card, from the Pop Series Five, which sells on average for £1,330.
