If you have secrets you prefer remain that way, or just feel like reliving the rush of Cold War espionage (nuclear fallout notwithstanding), then the Spy Coin Edition ITS Challenge Coin ($30) is for you. For this variant, ITS and Spy Coins began with a nickel plated solid brass coin, then hollowed it out to conceal a micro SD card as opposed to the microfilm Cold War operatives were known to sock away.

Today, there’s a thriving community centered around collecting these coins.
