[QUOTE="satootoko, post: 165200, member: 669"]The obverse(s) seem to match KM#74/74a, a copper or aluminum-bronze 10 Centesimi issued from 1936-43. They are very slightly wider than a US nickle. Chances are it was produced from two of those in either the standard magician's coin method of hollowing one out and machining another one down to fit the space; or the less common method of shaving the reverses off of two coins and gluing them together. Using a high-magnification glass, or a microscope, carefully examine the coin looking for either a cut line just inside the rim, or a joint line on the edge. Krause doesn't give a weight, so if possible the coin should be compared with a known genuine example of whichever metallic composition is invovlved. (Al-bronze generally has a Sacagawea dollar-like coloration). The "ring" test [u]might[/u] help also. Although neeither copper nor al-bronze sounds like a silver coin, they do make a clear metallic sound, while altered coins generally "thud".[/QUOTE]
