Proof-63 (PCGS).strongObv: /strongthe regular-issue obverse die of the datepstrongRev: /strongthe reverse with IN GOD WE TRUST as adopted in 1866pWarmly patinated on both sides, the surfaces are layered in generally even silver-olive iridescence. More direct angles reveal some variation to the toning, generally in the form of mottled pale gold, apricot, and silver undertones. Such angles also call forth a uniformly mirrored finish. The strike is razor sharp in all areas, and outwardly distracting marks are not seen. The uspatterns.com website calls this: "The so-called transitional half dollar using the reverse of 1866-1891. These and the other with motto patterns of this date and also 1863 and possibly 1865 are actually restrikes made circa 1869 and into the early 1870s and were offered with restrikes of the other denominations in complete sets." About a dozen examples of this rarity are thought to exist in silver. Of particular interest to specialists of the Liberty Seated series.p
