British Decimal Fifty Pence

Brief Description

An equilateral curve heptagon (seven-sided) coin featuring the second portrait of Queen Elizabeth II by Arnold Machin facing right. The inscriptions read 'ELIZABETH II D·G·REG·F·D·1969'

Historical Significance

This was the world's first seven-sided coin. It was introduced in October 1969 as part of the United Kingdom's transition to decimal currency, replacing the ten-shilling note. It is the largest of the common decimal coins and was revolutionary for its shape, which allowed it to be easily distinguished from round coins while still working in vending machines.

Estimated Value

$0.65 - $5.00 USD (depending on condition; circulated examples are generally worth face value or a small premium)

Care Instructions

Store in a cool, dry place inside a PVC-free coin holder or capsule to prevent oxidation. Avoid cleaning the coin with chemicals or abrasives, as this can strip the natural patina and significantly reduce its value to collectors.
