BOLIVIA. Cob 4 Reales, ND (1575-76)-P. Potosi Mint; Assayer Miguel Garcia (M). Philip II. PCGS Genuine--Salt Water Damage, AU Details.KM-4.1; Cal-521. Weight: 13.07 gms. This cob is most likely a shipwreck find, which accounts for the grade designation. Despite that, the coin must have been very lightly handled before its loss. The obverse shield shows much more detail than typical for a saltwater damaged coin. The denomination, mintmark, and assayer initial are clearly presented. The full, broad flan fully displays the legends on both sides.<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.
