Hollow Spy Coins

Bruce Schneier's blog links to a few sources for hollow spy coins, one being BoingBoing's Bazaar — where a nickel that can hold a microSD card costs $27. Another is Slashdot's sister company ThinkGeek, where you can get hollow quarters and half-dollars in the low 20s. As if corporate and government security geeks didn't have enough to worry about.

      That analogy doesn't work unless you're suggesting that you wouldn't use your wallet as a wallet. In this case, the coin is not really a coin. It's a fake, intended to deceive. On the other hand, I do agree with you that it seems like a slashvertisement.

      It wouldn't be that difficult to get the weight right, would it? I mean most coins are a copper core with a nickle covering. So if you could create a heavier core, it would compensate for the mass of the removed area. Actually, now that I look at it, lead would be the only non-expensive metal that's heavier than copper by volume, but it's not THAT much heavier (I'm not sure if it's enough to compensate for such a large void)... Sure, they could use something more exotic like Platinum or Tungston (or even Uranium or Plutonium, but if you use them in a coin, I think you have bigger problems than detecting a hidden microSD card), but how much would that thing cost then? http://www.simetric.co.uk/si_metals.htm

      Since these are machined out of gen-u-ine legal tender, the charge you would be worried about is defacement of currency, rather than counterfeiting.

      That said, I've never heard of anybody going after currency defacement operations(even the overt ones. Those "souveneir penny" machines that crush a graphic associated with whatever attraction the machine is located in have been around for decades, and the Secret Service has shown no signs of caring) unless they involve wholesale export of coins for their melt value(I think there was some issue involving the old pure copper pennies during one of the spikes in copper prices fairly recently).

      If you somehow got caught, and your hollow nickel contained a microSD card with a copy of secret_leaked_CIA_documents_that_the_illuminati_don't_want_you_to_have.doc, they'd probably throw a defacement of currency charge at you, just for completeness' sake; but, while almost definitely illegal, they aren't exactly a huge legal risk.

      I thought the illegal action was the "deBASEment" of the currency, not defacement. When coins were made out of precious metals, they could be shaved for bits and slivers of that silver or gold. Since the coins weighed less, but still represented the amount of money it was promised to by the government, the currency was debased. And that was a major crime. It defacement of the currency is illegal, then we would've locked up all those wheresgeorge.com people, who keep stamping one dollar bills.

Trying to "smuggle" a MicroSD card through is more likely to result in you getting caught and treated badly (even if it isn't even illegal).

Put innocuous data on one side, stick it in your camera, phone, music player, whatever. Even if the goons search the card, that's all they find.

  12. FBI Hollow-Nickel Story by kenh · · Score: 5, Interesting

    Hollow Nickel, Hidden Agent

    What’s a nickel worth?

    No, it’s not a riddle. It’s a case straight from the pages of FBI history.

    It all started in June 1953, when a Brooklyn newspaper boy picked up a nickel he’d just dropped. Almost like magic, the coin split in half. And inside was a tiny photograph, showing a series of numbers too small to read.

    Even if the boy kept up with the front page news on the papers he delivered, he probably never would have guessed that this extraordinary coin was the product of one of the most vital national security issues of the day: the growing Cold War between the world’s two nuclear powers, the U.S. and the Soviet Union.

    The coin ultimately made its way to the FBI, which opened a counterintelligence case, knowing the coin suggested there was an active spy in New York City. But who?

    New York agents quickly began working to trace the hollow nickel. They talked to the ladies who passed the nickel on to the delivery boy, with no success. They talked to local novelty store owners, but none had seen anything like it. A lot of shoe leather was ruined, but no hot leads emerged.

    Meanwhile, the coin itself underwent expert examination. FBI Lab scientists in Washington pored over it. They immediately realized the photograph contained a coded message, but they couldn’t crack it. The coin did yield clues, however. The type-print, Lab experts concluded, must have come from a foreign typewriter. Metallurgy showed that the back half was from a coin minted during World War II. Ultimately, the coin was filed away, but not forgotten.

    The key break came four years later, when a Russian spy named Reino Hayhanen defected to the United States. Hayhanen—really the American born Eugene Maki—shared all kinds of secrets on Soviet spies. He led FBI agents to one out-of-the-way hiding place, called a “dead drop,” where FBI agents found a hollowed-out bolt with a typewritten message inside. When asked about it, Hayhanen said the Soviets had given him all kinds of hollowed-out objects: pens, screws, batteries, even coins. He turned over one such coin, which instantly reminded agents of the Brooklyn nickel. The link was made.

    From there, Hayhanen put investigators on the trail of his case officer, a Soviet spy named “Mark” who was operating without diplomatic cover and under several false identities.

    After painstaking detective work, agents figured out that “Mark” was really William Fisher, aka Rudolf Abel, who was arrested on June 21, 1957. Though Abel refused to talk, his hotel room and office revealed an important prize: a treasure trove of modern espionage equipment.

    Abel was eventually convicted of espionage and sentenced to a long jail term. In 1962, he was exchanged for American U-2 pilot Francis Gary Powers, who had been shot down over the U.S.S.R. and held prisoner there.

    In the end, a nickel was worth a great deal: the capture of a Soviet spy and the protection of a nation.

    Considering the material of the inner wall is copper, it'd have to be a VERY strong field to penetrate the coin. It would have to be so strong that the induced currents are strong enough to begin to melt it. And actually the small size is an advantage, since you'd need a VERY high potential gradient to even generate a significant current (given the walls are how far apart? A tenth of a millimeter? Or on edge maybe a few cm at most). So basically you could generate a high power EMF that's oscillating at a very high frequency (to keep inducing high currents) over a VERY small distance (So that the generated EMF has a VERY high potential gradient) to even be able to generate any kind of a significant current... And by that point, if you melt the copper, you've pretty much destroyed what's inside, so the better option would be developing something to detect the seam rather than try to pear inside with EMR...
