KM-29. Middle year of a 3-year only issue and fairly scarce even in circulated condition. The coin becomes downright <strong>RARE </strong>at this level, especially when fully struck like the example offered here. An absolutely sensational example of the issue with full hair, and blazing white luster. For collectors of Argentinian or world crowns seeking the very best coinage available, this is a lot that should be pursued with gusto. NGC MS-62. From the Alex Siegel Collection.
