Hoarders take note, that box of old toys languishing in your loft could actually contain a sought after collectors item worth a small fortune.
An unopened copy of Nintendo’s Super Mario 64 has sold at auction for an eye watering $1.56 million (approx £1.12 million).
Heritage Auctions in Dallas said that the 1996 game sold on Sunday 11 July, breaking its previous record price for the sale of a single video game.
