Pedigreed to the Robert Mastalir Collection and plated on page 50 of Part A and page 172 of Part B of his books The Great Transition at the Potosi Mint, 1649-1652: The 1649-1652 Crowned Shield Coinage and the Countermarks of 1652 (2021), with copy of Moro certificate countersigned by Daniel Frank Sedwick.Recovered from: Capitana, sunk in 1654 off Chanduy, Ecuador.
