Yes, it is. And yes it does. A few dollars. One way to tell (but not always) is to look for the Blakesley Effect: http://koinpro.tripod.com/Articles/CurvedClipDiagnostics.htm It can also be faked: http://www.cointalk.com/t117464/
It could be. In fact it looks like a clipped planchet but I don't see the Blakesley effect (possibly due to less than perfect photos, especially the obverse photo with glare at 12:00). Do the last letters in UNUM flow toward the clip?
