Collective Nouns

Famous ones include "Murder of Crows" , "Parliament of Owls"  and a "Knot of Eels" but what is the collective noun for scars? For I am now collecting more scars.  I have a few ideas like a "Dermatology of Scars" or a "Pirate of Scars"  (after watching Black Sails) but the winner has to be a "Chest of Scars".  And I have the chest to prove it.

Ahhh another stab wound
