BOLIVIA. Cob 4 Reales, 1618-P. Potosi Mint; Assayer Pedro Martin de Palencia (RAL). Philip III. PCGS VF-30.KM-9; Cal-774; Paoletti-151. Weight: 13.31 gms. A <strong>RARE</strong> assayer with a distinctive monogram in place of a simple initial. This cob presents an impressively complete Habsburg shield on the obverse, with the mintmark and assayers monogram fully visible on the left. The well-centered reverse has lost detail in the center but remains crisp along the periphery. An intriguing example of this rather singular type.<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.
