Video: It's more fun to believe in a world where magic can possibly exist, but then you see a different camera angle of a cool magic trick and realise it's all just misdirection, tricks and fantastic finger dexterity. But still it's worth it just for that brief moment where you absolutely have no idea how the magician did that. Here's Oscar Owen teasing you with three tricks you can do with a coin — making a coin teleport, disappear and switch hands — and then crushing you as he explains how he pulls it off (it can be as simple as pushing the coin off the table).

Counterfeiting coins doesn't sound as exciting as pumping out ersatz $100 notes, but it is definitely a thing, especially in the UK where one in every 30 pound coins isn't the real McCoy. To battle this, over the next year the government will phase out the old coin for a shiny new one that incorporates "a high security feature ... to protect it from counterfeiting in the future".

Coins are supposed to sink. When you toss 'em in a fountain, they drop right down to the bottom, right? Not always. There's a trick that can actually make metal coins float, and it's totally trippy to see. You carefully level the coin (which needs to be made of aluminium and not zinc) onto the surface of the water with a paper clip, and then slide the paper clip away. Boom! You've just become a sorcerer. The metal coin is floating.

Video: One of my life dreams as a child was to be able to fool a vending machine with coin-like objects. I mean, how smart could a vending machine be, right? Wrong. More like how dumb a kid I was. Vending machines use light sensors to measure the size of a coin and electromagnets to detect the metal type to determine what kind of coin it is. If you're not shaped like a dollar and built like a dollar, you ain't a dollar in their book.

Video: The British Royal Mint makes three types of commemorative coins: bullion, brilliant uncirculated and proof. Bullion is basically made to the same standard of regular coins in circulation, brilliant uncirculated coins (a real mouthful) are finished with more attention to detail than bullion coins and proof coins are of the absolute highest quality and care.

How long have intelligence agencies been keeping tabs on the internet? And what role did these agencies play in creating the internet we use today? For the most part, these kinds of questions have been relegated to comments sections on random blogs and the occasional tweet from researchers. So we're hoping to remedy that in whatever small way we can, starting with a look at the 1960s and 70s.

I'm not aware of any anniversaries or other events that would warrant the release of a Star Trek-themed coin from Perth Mint, yet, from tomorrow the company will be offering 99 per cent pure silver currency with either the original Enterprise or James Kirk himself slapped on the front.

People of Earth, dreamers of the universe and possible alien organisms of the beyond: you can swim like Scrooge McDuck in a Swiss bank vault in real life. Like, literally swim in money. This is incredible. A bank safe swimming pool filled with 8 million Swiss coins is being auctioned off to the highest bidder who wants to fulfil every person's childhood (and adult) dream of swimming in money.

If you're a student or a young professional in your first apartment, you're probably well versed in assembling IKEA furniture. But those vital hex wrenches always seem to go missing soon after, and when it's time to move your bedroom set, it's off to the hardware store to find a replacement. So thank goodness the folks at Nendo came up with a better solution: furniture that assembles using nothing more than the loose change in your pocket.

The Man has his hand in your inbox and cops are intimidating citizens who film them beating other citizens. So it's only logical to want to keep the private contents of your SD card, well, private. The Covert Coin from CCS Spy Gear is a precision-machined piece of retired US currency that are nearly indistinguishable from the real thing when closed.
