CAC. One of the rarest dates in the series with a mintage of just 3,500 and relatively few survivors. This is a beautifully preserved example with needle-sharp detail on both sides and radiant mint luster. The obverse is flashy and semi proof-like with a frosty bright champagne-white core wonderfully framed by delicate peripheral rainbow toning. The reverse is just as stunning and champagne-white throughout except for a trace of iridescent blue and gold toning at the rim.
