1/2 Crown - Elizabeth II 1st portrait, no 'BRITT:OMN'

The omission of BRITT:OMN from the legend was a direct consequence of Indian independence and the subsequent dissolution of the British Commonwealth's older imperial structure. When George VI's coinage dropped the title in 1949, it marked the first substantive change to the British monarch's official style in decades. Elizabeth II's coinage continued without it from the outset of her reign, making any pre-1949 halfcrown the clean dividing line between imperial and post-imperial British currency.

Production ran through 1967, after which halfcrowns were struck only in 1970 for the final proof sets issued before decimalization abolished the denomination entirely on February 15, 1971.
