Asuncion mint, KM-Pn11 var., Peña-11 var. Most attractive for the assigned grade, a well struck and nicely toned Mint State coin with strong underlying luster and mild surface marks well within the confines of the technical designation. The only example seen by us of this variety featuring the “Paz y Justicia” motto on the obverse and no inscription other than the date on the reverse, it is also among and amongst the very finest extant of the 1864-1867 copper or bronze patterns of the 10 Reales denomination. When Jacques Schulman catalogued this and a similar coin struck in silver more than 100 years ago, he correctly indicated: ”The two (examples) of Pesos dated 1864 show evidence that the dies were broken, which is the explanation for the rarity of these pieces”.
Ex. Salbach collection (J. Schulman 9/1911, lot 2997) – lot 2996 was the aforementioned example struck in silver.
