Alfonso VII was crowned "Emperor of All Spain" at León in 1135 — a ceremony attended by tributary kings from Navarre, Aragon, and Portugal — and the Toledo mint's output during his reign carries the imperial title rather than the royal one used by his predecessors. The billon coinage from this period reflects the monetary pressures of sustaining near-constant military campaigning against the Almoravids along the Tagus frontier.
AB#94 is among the more frequently encountered types of his emission, though the variable silver content in surviving examples suggests the alloy was not held to a consistent standard across the Toledo mint's production runs.
