I have a 1978 Mexian Onza. I cannot find it in the online SCWC catalog. Anyone have any idea why it does not have a KM#?
Thanks. That is it. For some reason it is not listed in Numismaster under regular coinage but under Unusual Sources. I guess that is because it is considered to be medallic silver bullion and not a coin. I guess I have come to rely on the online version too much and don't pick up the printed copy enough. Normally I only do that when I want background information.
