PANAMA. 1/4 Balboa, 1953. NGC PROOF-66 Ultra Cameo.
KM-19. Mintage: 5 (estimated). A true RARITY, this enchanting proof issue, with an immensely small mintage, offers a delightful frosting to the devices along with immense mirrored brilliance in the fields. Just the slightest degree of haziness in a few spots on the obverse prevents an even higher designation, though, given the paucity in existence, is really of little to no consequence.
Estimate: $700 - $1000
