10 Reales Silver Pattern

Paraguay's monetary situation in 1855 was almost entirely theoretical — the country had no functioning mint and virtually no coined money in domestic circulation, relying instead on barter and foreign specie under Carlos Antonio López. This piece was produced as a pattern, almost certainly struck abroad, to demonstrate a proposed coinage system that never materialized in silver at this denomination. The 10 Reales unit itself is an oddity, sitting between the Spanish colonial real tradition and the decimal reforms sweeping neighboring Argentina and Brazil.

Fewer than a handful of specimens are documented across major collections.
