Watch List notes:

Lima, Peru, cob 1/4 real, Philip II, assayer X to right of castle, extremely rare, Proctor Plate Coin. S-L3; KM-2; CT-unl. 0.76 gram. Toned VF with full castle and lion and crowns, corroded from salvage but with the all-important assayer clear, very important as the only example we have seen (first ever offered at auction) and clearly the key for anyone assembling a denomination set, also significant as the first issue of this castle/lion-type cuartillo ever made. Pedigreed to the Jorge Proctor collection and plated on page 36 of his book The Forgotten Mint of Colonial Panama (2005).

Estimate: $1000 - 2000
