Hollow spy-coins milled out of real currency

A company called "Covert Coins" mills hollow coins out of real currency and turns them into hidden, spook-tastic secret compartments. Reviews say that the coins are indistinguishable from undoctored items on casual inspection.

    1. IIRC there are exceptions for small one-time uses like those penny pressing machines and whatnot. 

      1. And magic tricks: http://johnsonmagicproducts.com/shop/index.phpBut no, not a crime to destroy currency unless you’re doing so to commit fraud, i.e.pasting the ends of $10 bills on $1s, then turning in the mutilated $10s to be replaced. 

  1. can confirm, they are totally cool. Had mine for a couple years now and still can’t find a real use for it, but it’s great fun to show off.

  2. A chap in the pub showed me one of these £1 coins once… he’s an amateur magician and they’re used in tricks: for instance, you can hide a 5p piece inside. I think he said they cost about £20.

  3. Back in 2004 Canada minted a quarter with a colored poppy in the center. One of those coins caused a minor panic when it was found in the Pentagon, and believed to be some sort of spy device.

    When I first heard that story I laughed. Now it doesn’t seem so funny anymore.

    But are these hollowed-out coins any lighter? I know from experience that pound coins are noticeably heavy.

  4. Vending machines would reject it for being the wrong weight. A couple years ago a machine refused to take my quarter.  Eventually I figured out that it was pre-1965 and had a higher silver content. 

  5. Hide your valuable thing that people might want to steal inside… a valuable thing that people might want to steal.

  6. I wonder what it looks like under an xray machine? If you want to avoid the TSA taking a copy of your data at the border, could you come over with a pretty much blank laptop, and have the stuff you use on a bootable partition on a MicroSD card stored in one of those things?
