Collage Medallions measure 3" in diameter by 0.2" thick. They are most commonly used to commemorate a special event, an anniversary, a moment in history, or a new level of corporate achievement. They are available in solid, fine jeweler's pewter or brass plated alloy casting. Backside copy is provided at no additional charge; sequential numbering and/or optional pewter cast easels are available for an additional charge. These medallions are considered collector's items and often increase in value as time passes.
