Watch List notes:

Gold "oro corriente" cut piece, 23.55 grams, with full "f" stamp for Ferdinand V of Spain. Roughly 1" x ¾" x ¼". A narrow wedge cut from a gold ingot for circulation and trade, the three cut sides sharply sliced and the top and bottom surfaces fairly smooth, the top stamped with full and bold "f" inside rectangular cartouche for Ferdinand V of Spain (an unusually complete and sharp stamp), next to scattered raised dots from traces of the "quinto" tax stamp, including a visible letter A, tying the piece directly to crown-controlled bullion from the very early 1500s (when coins were not being made in the New World), hence among the earliest gold traded in the Americas and very rare as such, especially with such full and visible stamps, in fact identical to those seen on pages 20-21 of in García-Barneche's Tumbaga Saga (2nd ed., 2018). XRF analysis confirms 22K fineness with multiple trace elements, consistent with early New World alluvial gold. Based on weight, this piece no doubt circulated at a value of seven escudos.

Estimate: 5000 - 10000 USD
