What Does Od Mean For In Medal Working

Complete Explanation

In medal working – the process of designing, engraving, striking, and finishing medals – the abbreviation “OD” is most frequently used to denote the obverse die or obverse design. The obverse is the front side of a medal, typically bearing the principal imagery such as a portrait, emblem, or inscription. Referring to the “OD” allows craftsmen and documentation to specify which die or design is being discussed, especially when contrasting it with the “RD” (reverse die) that creates the opposite side. The usage of “OD” is standard in technical specifications, production logs, and collector literature, although its exact expansion may vary slightly among different manufacturers or regions.

• Primary meaning:
  OD most commonly stands for “Obverse Die,” the metal die used to strike the front (obverse) side of a medal.
• Alternative wording:
  Some sources use OD to mean “Obverse Design,” emphasizing the artistic layout rather than the physical die.
• Contextual usage:
  In production notes, “OD” appears alongside dimensions, material specifications, and engraving details to clarify which side is being referenced.
• Distinction from RD:
  RD indicates the “Reverse Die,” the counterpart that creates the back side of the medal; together, OD and RD describe the complete set of tooling required for a medal.
• Variations:
  While less common, OD can also appear in uniform regulations to denote “Order of Dress,” but this meaning is unrelated to medal manufacturing.
