ARGENTINA. La Rioja. 1/2 Real, 1854-B. La Rioja Mint. NGC MS-64. KM-25. Mintage: 71,000. Variety with CRED-PUB-DE LA RIOJA legend. Virtually tone free and very sharply struck for the issue which results in a bold rendering of ever-popular sunface design that sits atop the arms of Argentina. Quite notable as the single finest example of this variety thus far certified by NGC. From the Matthew Orsini Collection.
