Watch List notes:

Seville, Spain, gold bust 8 escudos, Charles IV, 1798 JN, contemporary counterfeit made in gilt platinum, ex-J.O.B. 27.03 grams. Sharp AU details that are fairly close to correct but not enough to fool someone knowledgeable, a few small marks, the gilding a bit faded but still mostly gold in color, tiny hole at top so perhaps intended for jewelry all along as opposed to being a contemporary deception (when platinum was worth far less than gold). XRF tested at Pt 59%, Au 36%, Cu 1.9%, Ag 1.6%. Pedigreed to the J.O.B. Collection and to the Heritage Auction of August 1996 (lot 7806), with collector's tag.
