1893 Isabella Quarter. MS-66 (PCGS).This is a delightful example with a heavily silken complexion throughout. A flurry of olive-copper, cobalt blue and dusky rose patina blankets both sides, delivering a fittingly regal aesthetic. The 1893 Isabella quarter was our nations first commemorative issue in this denomination, and with most examples grading MS-63 and MS-64, a gorgeous premium Gem example such as this is a real treat.
