Many of the visitors who arrive at Collector’s Cardhouse come with large binders tucked under their arms filled with cards they stashed away in their childhood.

Many of these collections are, unfortunately, not worth anything.

If, however, PokiChloe does deem a card valuable, it then has to be “graded”.

The process involves sending the card to a grading company who analyse it for signs of wear and then award it a graded score, usually out of 10, which denotes its quality and potential value.

PokiChloe compared those cards that get a 10 to “gold dust”.

“It has to be completely clean,” she says.

“There can’t be scratches on the holographic part, there can’t be any whitening or damage on the back, it can’t be creased. It has to be perfect like it’s never been touched before.

“We had a Charizard that was graded a 10. It was a special card that was given out to employees at Creatures, who own Pokémon. I think there’s only 300 of them and we had a 10 and we sold it for just under £40,000.”
