[QUOTE="masterswimmer, post: 24681352, member: 102022"]If I can chime in with my $.02. Copper and zinc are both very soft metals. On the Mohs hardness scale where 1 is the softest and 10 is the hardest, both zinc (2.5) and copper (3.5) are in the 2.5 to 3.5 range. For the record, your fingernail is a 2.5 on the Mohs scale. That info should be enough to explain how incredibly easy it is for these coin metals to be manipulated and malleable enough to distort the devices on a copper/zinc coin to appear to the untrained eye as an error. Add to that, there is no way during the minting process for the distortions you're pointing out to occur. Hence the accurate assessment by [USER=44615]@paddyman98[/USER] [USER=111067]@expat[/USER] and [USER=43872]@Neal[/USER] [ATTACH=full]1574448[/ATTACH][/QUOTE]
