Relating to or located in the exergue, the space on a coin or medal below the main design.
From exergue + -al suffix. Exergue itself comes from Greek ex- (out) + ergon (work), originally meaning the part 'outside the work' on a coin.
Coin collectors use 'exergual' to describe features in that tiny space at the bottom of coins—experts can date coins by reading the engraver's initials or dates in the exergual area.
