KM-161.5, 1891 Bolivia 50 centavos, CB essayer, Potosi mint (PTS mintmark in monogram); silver, reeded edge; almost uncirculated, an archtypical Bolivian strike of the period - almost uncirculated for wear (fastest worn areas will be wreath leafs on reverse and the sun and llama on obverse) combined with the flat breasted (raised) and flat headed (in depression) condor - probably rusted/worn out dies.
