1926-S Standing Liberty Quarter. MS-66 (PCGS). Intensely lustrous surfaces are brilliant in the centers and lightly toned around the peripheries in iridescent copper-rose patina. It is expertly preserved and solidly graded as an upper end Gem. The 1926-S quarter is a key date issue in the Standing Liberty series in all Uncirculated grades, even at in MS-60 to MS-63. In MS-66 this issue is highly elusive and seldom offered. Once again, as so often with our Pogue Collection offerings, the word opportunity is paramount.
