1 Shilling - Charles I Group F, 6th bust

Group F shillings were struck at the Oxford mint, established by Charles I after he raised his standard at Nottingham in 1642 and found London — and the Tower Mint — firmly in Parliamentary hands. Oxford became the Royalist financial engine, melting down college plate donated by the university to fund the war effort. The 6th bust is the most frequently encountered of the Oxford issues, but surviving examples with full, even strikes are genuinely scarce; the improvised mint conditions and recycled silver produced notoriously inconsistent planchets.

Spink 2800 encompasses considerable die variation. The mint mark sequence across this date range helps narrow striking to specific campaign years.
