Lucy Hughes has turned her nostalgic "hobby" into a six-figure salary.

The Sydney woman, 36, was an early adopter of buying and selling rare Pokémon cards, a revived Millennial trend that is netting some people millions of dollars.

Hughes uses eBay to trade thousands of popular cards online and is earning more cash from it than her full-time job.

Do you have a story? Contact reporter April Glover at Wrestler and YouTuber Logan Paul broke a world record this week when he sold his ultra-rare Pikachu Illustrator card for $16.5 million ($23.3 million) during an auction.

"Sometimes it can come down to luck, if you just so happen to have the card," Hughes said.

The Japanese cartoon's 30th anniversary is approaching on February 26 and Hughes expects there to be a trading frenzy.

"Pokémon always finds a way of trying to reconnect with its fans, I have no doubt they'll come out with products that are all about nostalgia," she said.

Hughes is hosting another live-streamed auction on eBay on February 26 to mark 30 years of Pokémon.
