Silver Britannia 1 oz
United Kingdom · silver · 2013-today (999 ‰)
Overview
The Silver Britannia is the silver bullion coin of the Royal Mint, struck at 999 ‰ since 2013, after years at a lower fineness. It takes up the figure of Britannia standing, helmeted, holding trident and shield, drawn by Philip Nathan for the series; the obverse carries the effigy of the sovereign. The coin weighs 31.21 g, of which 31.18 g of fine silver, one troy ounce, with a diameter of 38.61 mm and a thickness of 3 mm. Recent strikes include the same security features as the gold version: a latent image, micro-text and an animated background of wavy lines, visible when the coin is tilted. Like any fine silver coin, it may haze or spot slightly over time without losing any metal; the original tube or capsule protects it. At Gold & Silver Company in Dottignies, every Silver Britannia is weighed and appraised in front of the person, like the gold coins; the assay in the agency is what counts.

How to check it
Indicative check: weigh the coin to the centigram and measure its diameter with callipers; a deviation of more than 0.1 g or 0.2 mm from the reference values warrants an examination in the agency. The assay in the agency is what counts.
