Okay, so you’re now officially a coin detective. Congratulations. Here’s your simple checklist: Flip it over and look at the back design. Is it a thistle? A leek? A strange swirl that might be a DNA strand? Good. Now check the year. Coins from 2011 (the Edinburgh one) and 2012 (the Olympic high jump) are your prime suspects. Also, look for any silly little errors, like a misprint or a weird edge. Even a slightly dodgy-looking coin can be worth a fortune to the right nerd—I mean, collector.
Another trick: weigh it. Old pound coins should weigh exactly 9.5 grams. If yours feels a bit heavy or a bit light, you might have a forgery—and yes, counterfeit coins are a thing! But ironically, some of those fakes are now collectable, too. Because the world is mad, and we love it.
