PCGS authenticated and graded XF 40. Deep brown and maroon with fine granularity on the surfaces. There are also a couple dull hairline scratches from below the crown to the harp. Nicely struck with sharp details and nice bold legends and a rim break at 3 o'clock on the reverse. This is the only example of what appears to be a unique die pairing in the 2018 Martin reference, plated for both the obverse and reverse on pages 109 and 259.
