Concordant
Concordant. The relationship of a medal's reverse to its obverse, where the reverse is the back of what the obverse would be, as if the medal were sculpture in-the-round. A recent example is a Lincoln Medal for the Lincoln Memorial University by Albert d'Andrea (71-139); another is the Society of Medalists Issue #15, Love by Robert I. Aitken (30-1-15).
