KM-92 (Plate Coin); Jovel-Type V C/M. Type II sun over mountains countermark on a 1830-JL Bolivia 4 soles. <strong>VERY RARE</strong> host coin and denomination especially so in this state of preservation. Initially applied from 26 April 1839 through 20 November 1840 to cob coinage of good weight and purity. Then applied to Pesos Fuertes from May to 29 June 1840 and on the milled coins of 2, 4 and 8 Reales from Bolivia and Peru, before the Peru-Bolivian confederation, from 31 October to 20 November 1840. According to Jovel the assayers erroneously countermarked the present example because of the lack of compliance with weight requirements. A lovely example that is far and away nicer than most specimens seen on the market. It may take many years before another specimen this nice appears. Light attractive iridescent tone. Sure to excite the specialist of Guatemala or World countermarks. NGC AU-55.
