New sovereign and half sovereign coins were introduced in Britain 1817, and by 1828, Samuel Harrison, of Birmingham, was advertising an “improved Sovereign Balance” designed to determine if a coin is counterfeit or not. The "Harrison" maker's mark on this example appears on the beam near the crown. The plates for the coins are marked "Sovereign Warranted" and "Sovereign ½." The scale is contained in a small box made of paper. A signature, in ink, reads "Robert Naisey Chemist Marlboro Westshire 1842."
