Then you could be sitting on a goldmine, friend. Find out* by bringing your old tat along to the Gaming Antiques Roadshow, which is rolling into the Eurogamer Expo on Saturday 24th September.
Self-appointed experts John Teti and Ellie Gibson will be on-hand to evaluate your treasures. Whether it's a Kojima-signed copy of Metal Gear Solid or a potato which looks a bit like Sonic the Hedgehog, we will tell you what it's worth in today's money.
Evaluations will be filmed and shown on this here Eurogamer.net. If you'd like to take part, please email email@example.com. Kindly state what it is you'd like to bring along and confirm that you're happy to appear on camera.
Hope to see you, and your bobby dazzlers, at the Expo!
