Your reference to the web site on coin spoons reminds me of a cigarette extinguisher I once saw. It was made during World War II in the German-occupied Netherlands of three coins soldered together—at the bottom a square copper-nickel five-cents piece, standing thereon a round bronze cent, and at the top one half of a bronze half-cent, which had been cut in half, to fetch the object.

These coins had been demonetized by the German high commissioner Arthur Seyss-Inquart and replaced by zinc coins, to obtain strategic materials like copper-nickel and bronze for the German war effort. The extinguisher was fashioned as a protest against this measure and to ridicule the hated Seyss-Inquart: the coins with a total nominal value of six-and-a-quart cents impersonated the high commissioner's nickname Six-and-a-quart.
