The butterfly is the symbol for change. This stunning premium coin says If Nothing Changed There'd Be No Butterflies recessed around the rim, then colored in metallic Reflex Blue color with a translucent herringbone pattern under the fill. The glossy gold plated butterfly is a raised 3D design and on the back of the chip you'll find the Serenity Prayer. Size of the medallion is 33mmx3mm a full 1mm thicker than standard coins for a premium weight and "feel". Great gift for anyone going through a life change like graduation or living a life of sobriety or entering recovery.
