Having been raised in Argentina, I bought this pattern a few years ago before deciding to switch over to Argentine currency to fill my collecting needs. Listed in Krauses Standard Catalog of World Coins as Pn-20, this piece was authenticated, encapsulated and graded Uncirculated Details, Net About Uncirculated 50 (Cleaned) by ANACS, a leading third-party grading service. Struck slightly off-center, this hard to find piece would be a nice addition to any serious collection of South American or world coins.
