1873 Liberty Seated Half Dollar. Arrows. Proof-63 (PCGS).The frosty champagne and steel-gray devices of this Choice Proof offer a tranquil contrast to the slate-gray and cobalt hues across the reflective fields. The Arrows type is important and in high demand; this particular feature was added to the obverse design to designate the slight alteration to the silver content of the planchet. A mere 550 were coined in Proof, with this attractive coin well suited to represent this desirable issue.
