Silver Britannia
Sizes and Weights
The Silver Britannia, first introduced in 1997, is available in multiple weights beyond the standard one-ounce. These include fractional options such as half-ounce, quarter-ounce, tenth-ounce, twentieth-ounce, and even a twenty-fifth-ounce variant. Since 2013, these coins have been produced with a .999 fine silver purity. Both proof and bullion versions are released annually, with proof coins often offered as part of special sets. The variety in weights and the coin’s intricate design make the Silver Britannia a popular choice for collectors and investors alike.
