1893 Isabella Quarter. MS-67 (PCGS).This is an exceptionally smooth and well preserved example of the historic Isabella quarter commemorative. Lustrous and frosty surfaces are sharply struck with richly original toning in blended charcoal gray, powder blue and pale gold. This design type by Charles E. Barber, the first -- and until the 1776-1976 Washington quarter, the only -- commemorative quarter dollar was made at the behest of the Board of Lady Managers of the Worlds Columbian Exposition, of which Susan B. Anthony was a member. The coin was authorized March 3, 1893, and production began almost immediately afterward. As current certified population data shows, the number of survivors thins dramatically at and above the MS-67 grade level. This is a virtually pristine and highly appealing coin that is worthy of the strongest bids.
