I haven't yet got Krause for the 18th Century, so pls help me identify this coin I just bought. Belgian seller says he found it on the battlefield at Waterloo. Silver? 3.7 g, 25 mm. Obverse: Crowned coat of arms and legend ARCH.AUS.DUX.BURG.BRAB.C.EL Reverse: Floriated cross, date 1751, and legend MA.(B/R?).TH.D.G.R.IMP.?ON.BOP.R. (B/R?) means I can't make out if its a B or an R, and ?ON means I can't make out the letter before ON. Any help is welcome.
It seems to be a 10 Liards coin, minted in the Austrian Netherlands (present day Belgium), in the name of Maria Theresa (per Krause). The material is billon. The value is approx. $10 in that condition.
As for the legends... MAR(ia) TH(eresia) D(ei) G(ratia) R(omanorum) IMP(eratorem) G(ermania) HUN(garia) BOH(emia) R(egina) and ARCH(idux) AUST(riae) DUX BURG(undiae et) BRAB(antiae) C(omes) FL(andres) meaning: Maria Theresia by the grace of God Roman Emperor, Queen of Germany, Hungary and Bohemia, archduke of Austria, duke of Burgundy and Brabant, count of Flanders. Mintmark is a small lion, being the mintmark of Bruges.
