The Covert Compass from Shomer-Tec is a genuine nickel that has been modified to function as a simple compass that will point to magnetic North. The nickel has a groove around the edge that is used to suspend the coin from a thread. You supply the thread and when dangled, the heads side of the coin will point the way North. This extremely basic compass was inspired by similar compasses used by allied service men in WWII. No one would guess that this coin is a compass, making it the perfect addition to your spy gear toolbox. The Covert Compass is available from Shomer-Tec for $24. They also offer a Euro coin version for $29. They are going to send me one to try, so l’ll have a full report soon.
