BOLIVIA. Cob 4 Reales, 1618-P. Potosi Mint; Assayer Juan Jimenez de Tapia (T). Philip III. PCGS Genuine--Salt Water Damage, VF Details.KM-9; Cal-776. Weight: 13.28 gms. A wonderful cob recovered from the <em>Atocha</em> shipwreck of 1622. Despite the saltwater damage caused by its centuries under the sea, this piece is replete with identifiable details. On the obverse, the Habsburg shield is quite well-centered and retains satisfying detail. Beside it, the mintmark and initial from this <strong>SCARCE</strong> assayer remain quite clear. The reverse displays enough of all four digits of the date to positively attribute this coin to the year 1618. An excellent piece of shipwreck treasure.<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><p>Ex: Atocha.
