As one card recently sold for £12m, opportunistic thefts have surged – envelopes are being opened en route, costing small businesses thousands

Pokémon’s success over the last 30 years has seen it grow from a much-loved Game Boy classic, to a world-dominating brand with TV shows, spin-off games, toys and even a theme park. The trading card game is a huge part of that, with more than 85bn cards printed over its lifetime, and the appetite for them shows no signs of slowing down. Packs get snapped up after release so quickly it’s now almost impossible to find them in shops, and a booming resale market is driving the hobby into murky waters.

One card recently sold for an eye-watering £12m, and an increasing number of people have gotten into the collecting business on the hunt for huge profits, leading to a rise in thefts targeting card shops. More recently though, some small businesses have reported that their sales have been hit by thieves targeting envelopes within Royal Mail, leading to thousands in lost revenue.

A surprising economic bubble is making it hard for anyone to buy Pokémon cards – especially children

Pokémon has been huge since the late 90s. Millions of people have fond memories of playing the original Red and Blue games, or trading cards in the playground for that elusive shiny Charizard (if your school didn’t ban them). The franchise has only grown since then – but, where the trading cards are concerned, things have taken an unexpected and unfortunate turn. It’s now almost impossible to get your hands on newly released cards thanks to an insane rise in reselling and scalping over the past year.

Selling on your old cards to collectors has always been part of the hobby, and like baseball cards or Magic: The Gathering, Pokémon cards can sometimes go for thousands of pounds. However, the resale market for Pokémon has climbed so high that even new cards are valued at hundreds, before they’ve even been released. The latest set, Phantasmal Flames, had a rare special illustration Charizard that was being valued at more than £600 before anyone had even found one. When a pack of cards retails at about £4, there’s a huge potential profit to be had.
