One of the dessert cups is a darker color amber then the other 7 I included picture side by side unsure why maybe the way it was cast

This set of eight Indiana Glass dessert dishes is a true treasure for any collector of vintage glassware. The round, amber-colored dishes feature a glossy finish and are adorned with the Kings Crown Thumbprint pattern. Each dish is 3 inches in height, 3.5 inches in width, and has a diameter of 3.5 inches.
