THE BOYLSTON COLLECTION, PART IV A bold watery GEM! Untoned gleaming mirrors are highly reflective and flashy, sleek as a sheet of freshly polished glass. The devices show crisp, full, razor sharp definition and there is a hint of contrast between the frosty devices and mirrored fields. A few ancient lines can be found with effort, but many of them are on the holder and not on the coin. Untoned and fully brilliant, this gem has a great look. Only 600 Proofs were struck. PCGS 14, NGC 18. The most recent examples sold for $2,400 (June 2020 and February 2018). The current Collectors Universe value is listed at $4,000. RARE finer, this coin will delight any collector.
