1 Crown - Charles II 2nd bust

The Second Bust crown was introduced as part of a broader retooling of the Restoration coinage following persistent complaints about the quality of hammered silver still circulating alongside the new milled issues. Charles II's Treasury was simultaneously fighting a losing battle against clippers — criminals who shaved silver from hammered coins — and the 1663 introduction of milled edges on crowns was a direct countermeasure. The years 1664–1666 place this coin squarely in the run-up to the Second Anglo-Dutch War, during which the Crown's finances were under severe strain.

The Second Bust variety replaced the First within a year of its introduction, making the combined 1664–1666 run relatively brief.
