We have handled a few really great GEM PROOF 20C pieces in our time, we can honestly say this piece does rank among the best! It's only a few light well-hidden lines from PR66. The mirrors are deep, clear, clean, and have strong reflectivity. They look like a freshly formed sheet of ice when twirled. A beautiful mix of totally original blue/violet/gold/green colors is evenly spread all over. Miss Liberty and the details are thickly frosted and have crisp full strikes. The eye appeal is like the quality: superb! ONLY 350 were minted for this rare PR ONLY date. PCGS 29, NGC 23, CAC 9. The current Collectors Universe value is $14,000. We sure haven't seen many of these lately! Cert. Number 43980269 PCGS # 5305
