Random title: Breast feathers
Explanation: The central feathers seen on numerous eagle designs. Fully struck coins usually command a premium and the breast feathers are usually the highest point of the reverse. (They are the most deeply recessed area of the die, so metal sometimes does not completely fill the breast feather area, usually because of insufficient striking pressure. Incorrectly spaced or lapped dies will also cause 'striking' weakness)
