Republic gold 100 Soles 1968 MS64 Prooflike NGC, Lima mint, KM231. Choice Mint State with fully reflective fields and minute contact marks preventing it from reaching the Gem class. A much scarcer date of the type -mintage is of only 540 pieces - in very rare technical certification, the only example of the date currently certified as Prooflike and certainly worth a significant premium as such.
Estimate: 3000-3500 USD
