Subtle shades of blue, antique grey and rose are fired by underlying luster. The surfaces are virtually free of contact marks. The square-base `20 over `19 in choice AU is a prize for advanced collectors. It is distinctly tougher to find than its curl-base counterpart. CAC has approved only 3 examples graded AU 58, half the number of curl-base overdates. Last seen in Legend’s New Orleans Regency Sale XVII, May 2016, lot 200 as “O.101a.” It brought $4,852.50.Est. $4,500 to $5,500.
