United Kingdom, Great Britain, Proof Silver 25 Pence, Queen's Silver Jubilee, 1977, 28.3g, 38.6mm, (KM # 920a), Proof.

Issued to commemorate the 25th anniversary of the Queen's accession to the throne in 1952. This crown, as with the 1977 crown, had a face value of twenty-five new pence. Because it was primarily a commemorative coin rather than being intended to circulate, it was presumably not considered necessary to include a mark of value in the inscription.
