1/4 Real - Carlos IV without mintmark

Chile's colonial mint at Santiago produced this denomination without a mintmark during 1792–93, an anomaly in an otherwise consistently marked output. The omission was not policy — it reflects a transitional period in die preparation at the Santiago casa de moneda, where administrative and personnel changes under the late Bourbon reforms occasionally disrupted standard production protocols. Survivors are scarce precisely because the type's brief window accounts for very low overall output, and the small flan size made these among the first coins to disappear from circulation through loss and attrition.
