Gorgeous iridescent toning blankets luminous mirrored surfaces that are essentially mark-free. A thoroughly pleasing example of the design created by Mint Engraver Charles Barber for dimes, quarters and halves. PCGS 11, NGC 25. Only 11 finer. The PCGS price guide is listed as $3,500. Most recent auction record for an NGC Prooff was $2,574 in September 2017. A pretty coin worthy of a premium bid. Cert. Number 1883546004 PCGS # 5687
