Hi, I would like to know what caused the letters “BER” to have what look like barbs coming off of the letters. If pictures of the complete obverse or reverse are needed, I will post them. Thanks!
My guess is a worn die. As it wears, the edges of the concave letters crumble and form that "doubled" looking effect. Wit for others.
Trail lines are caused by a worn die. Referred to as Die Deterioration Doubling (DDD). You can learn more about it on this site: http://www.error-ref.com/?s=die+deterioration+doubling
Inclusive of radial flow lines from the die deterioration, it's making the machine doubling look spiky: http://www.error-ref.com/radial-flow-lines/
