This specimen was lot 71189 in Stack's Bowers Collectors Choice sale (Costa Mesa, CA, November 2022), where it sold for $384. The catalog description[1] noted, "BOLIVIA. Cob 4 Reales, 1718-P. Potosi Mint; Assayer Diego de Ybarbouru (Y). Philip V. PCGS EF-40. This 4 Reales Cob is impressively original. Its obverse displays a denomination and a bold date in the center. Though the peripheries become flat, a mintmark and assayer are decipherable. The reverse does not retain any details due to flatness and the rather ragged flan, but offers a charming cross with castles and lions. This piece is enhanced by a beautiful old cabinet tone. From the Pat Johnson Collection. Privately purchased from Mike Dunigan." This type was struck for Philip V through his entire reign. Assayer Y stamped coins 1701-28. The silver cobs were debased from 0.931 fine to 0.917 fine in 1728.
Recorded mintage: unknown.
