1893 Isabella Isabella Quarter 25c Grades Unc Details. When Examining an Isabella Quarter on the Obverse, wear first shows in the area of the Crown’s Central Oval Jewel and on Isabella’s cheek. Reverse wear will first be noted on the Strand of Wool Resting on the Kneeling Spinner’s Thigh. Due to Die Wear, Raised or Sharp Definition of the Strand of Wool is not the norm. This area can display a Slight Weakness of Strike, which is par for the Design and should not be Labeled Wear.
