4 Reales - Charles II Segovia, without Portugal arms

Charles II's coinage of the 1680s reflects a monarchy in administrative disarray — the king was chronically incapacitated, regencies had fractured central authority, and the mint apparatus at Segovia operated with considerable autonomy. The "without Portugal arms" designation traces to the formal renunciation of the Portuguese succession claim following the 1668 Treaty of Lisbon, after which some Castilian issues dropped the Portuguese quartering from the royal arms entirely, though application across mints was inconsistent for years afterward.

Segovia's water-powered mill, the Real Ingenio, gave it a mechanical minting advantage over most Spanish facilities — pieces from this mint tend toward more uniform planchets than hand-struck contemporaries from other houses.
