BOLIVIA. Cob 4 Reales, 1667-P. Potosi Mint; Assayer Antonio de Ergueta (E). Charles II. PCGS VF-35.KM-25; Cal-510. Weight: 12.44 gms. This deeply toned cob is struck on a somewhat short flan but offers enough detail and eye appeal to satisfy. The obverse shows rather clear denomination and date in the central devices, along with a decipherable assayers initial. Although no mintmark made it onto the obverse, a clear one appears on the reverse alongside another denomination mark. A piece with much remaining charm.<strong>To view all items from the Pat Johnson Collection, click <a href="https://auctions.stacksbowers.com/lots?sort=auction_date_lot_number_asc&search=From+the+Pat+Johnson&limit=96&parent_category=1-11EIV&lots_range=upcoming"> here.</a></strong>From the Pat Johnson Collection.<p>
