One of the oldest mechanical devices known to man, the cogwheel, also known as a cog or gear, really came into its own during the Industrial Revolution. Even in the era of advanced technology, modern machinery still uses the ancient concept of cogwheels to transmit or receive motion.
Cogwheel Shaped Coins
Struck in the shape of cogwheels, the eye-catching silver coins in this set both feature 12 teeth. With reverse designs portraying a series of cogwheels, they have been ‘antiqued’ for a unique aged appearance.
Case with Rotating Mechanism
Certain to appeal to those with a mechanical mind, the coins are presented in a transparent acrylic display case containing a winding mechanism which allows collectors to rotate the coins with a small winding handle (supplied). Housed in a superbly illustrated outer case, the set is accompanied by a numbered Certificate of Authenticity.
