This piece pushes the boundaries of what is possible as now Both sides feature incredibly high relief in Proof finish! High relief that has been pushed to levels 100% higher than what was previously possible. Check out the contrast between the relief of the Eagle’s claws and the incus depths its marks leave in the surface of the fields! The claw literally looks like it is ripping through the metal and coming right out at you! Also notice how the high relief of the Eagle’s head extends to the edges of the coin instead of just the center.
