Exact quantities of these proofs are unknown, though supporting evidence in the form of the relatively SCARCE nature of their appearance on the secondary market makes it a fair summation to call these pieces VERY RARE. It is doubly unclear if these were produced for export to China with the business strikes or were made for collector demand elsewhere. PCGS has certified ten examples of the 20 Cents and 10 Cents in proof, and eight examples of the 5 Cents. All examples contained in this group display a cameo nature, with light frosting on the devices and biting contrast from the mirrored fields. As Gem examples, all pieces avoid handling or friction, and are completely engaging to the senses. The last time we have offered even a single proof example of any of these denominations was back in 2019, showing just how elusive these proofs are. Given the complete nature of the set, it is virtually assured this grouping with generate strong bids and much attraction.
