19th Century Tokens, Warwickshire, The largest copper coin ever issued in Great Britain:
Birmingham, Workhouse, Pattern (?) Sixpence, 1813, by T. Willets, in copper, frontal elevation of building, rev. arms, edge plain, 163.62g/6h (W 375). Minor flaws on rims, otherwise very fine and extremely rare, believed only seven specimens known (£600-800)

This huge coin, weighing five and a half ounces, owes its probable existence to the temporary low price of copper relative to silver at the time (cf. Noble I, lot 1921, note)
