The 2013 1oz Silver Britannia Bullion Coin is a major transition year for the series, as it was the first standard Silver Britannia bullion issue struck in .999 fine silver. This change brought the coin into line with other leading international silver bullion programmes.
The reverse continues the Britannia theme, while the obverse carries Queen Elizabeth II's portrait. The move from .958 Britannia silver to .999 fine silver gives the 2013 issue particular importance within the modern history of the series.
Collectors often view 2013 as the start of the second major Silver Britannia bullion era, making it a key date for both bullion buyers and complete date-run collections.
