1 Real - Fernando VI

Fernando VI's reign saw the Lima mint navigating the aftermath of the 1750 rebellion led by Juan Santos Atahualpa in the central highlands, which disrupted silver supply routes from the interior. Production continuity at Lima was maintained, but the political pressure on colonial administration during these years was considerable.

The KM#42 type belongs to the cob — macuquina — tradition, hand-struck from roughly cut planchets. Lima was among the last major mints in Spanish America to transition away from this method, finally abandoning it in 1751 in favor of milled coinage.
