Potosi, Bolivia, cob 8 reales, (161)7M, possible contemporary counterfeit. S-P19; KM-10; CT-129. 22.73 grams. Exceptional full shield and cross with much legend (full king's ordinal III and bold [A]NO D [161]7 of date), AVF with flat areas and green spots, very broad flan with unmolested edge and clearly circulated but so low in weight that we have to offer up the possibility that it is a contemporary counterfeit.
