Struck off-center enough to enable a very bold 13 of date in addition to a full crown and just enough mintmark to attribute it to oM instead of oXM, the shield and cross partial but crisply detailed due to its exceptionally high grade, with corresponding luster, peripheral flatness. From the The John Pullin Collection of Dated Mexican Gold Cobs from the 1715 Fleet. The Nieves site of the 1715 Fleet, pedigreed to the Parke-Bernet auction of February 1967, lot #173 (plate photo on page 65 of that catalog). Auction lot-tag personally signed by John Pullin.
