Peru 1961-ZBR libra
This specimen was lot 1854 in Stephen Album sale 27 (Santa Rosa, CA, January 2017), where it sold for $470. The catalog description noted, "PERU: AV libra, 1961. Initials ZBR, better date, semi-prooflike, mintage of only 402 pieces! NGC graded MS64, R." The gold libra superseded the silver sol as Peru's main unit of currency in 1898. The libra weighed the same as a British sovereign and equalled ten soles. The type was struck 1898-1930 and again 1959-69, along with 1/5 libras and half libras. By 1962, the libra was no longer a circulating coin but a bullion unit, minted to circumvent U.S. regulations on trading in gold.
Recorded mintage: 402.
Specification: 7.99 g, .917 fine gold, .2354 troy oz AGW.
Catalog reference: Fr-73, KM 207.
