Republic gold 50 Soles 1957 MS64 Prooflike NGC, Lima mint, KM230. One of just two prooflike examples of this date certified by NGC, and the finer of the two. We sold a regular MS64 in September, 2015 for $1,000 hammer, though we suspect that the "prooflike" designation will add a significant premium to this coin.
Estimate: 1000-1500 USD
