1989 Medal C.S.N.A. 85th Convention Anodized Aluminum

Coin Details

Description

This 1989 medal commemorates the 85th Convention of the California State Numismatic Association, struck in anodized aluminum — an unusual composition that distinguishes it from the brass and bronze medals typically produced for C.S.N.A. conventions. Anodized aluminum is a lightweight material that can be produced in various colors through the electrochemical anodizing process, giving medals a distinctive appearance that differs markedly from traditional copper-alloy pieces. The choice of anodized aluminum for the 85th convention medal may reflect either aesthetic experimentation or a desire to create a visually distinctive issue for this near-milestone gathering. The C.S.N.A.'s 85th convention medal adds variety to the organization's long-running convention medal series, which spans decades and encompasses multiple compositions. Anodized aluminum medals are collected as a distinct category within numismatic society memorabilia, prized for their unusual material and the range of colors achievable through the anodizing process. The 1989 date places this convention during the height of the Wall Street-era coin market boom, when investment money was flowing into numismatics and convention bourse floors were experiencing strong commercial activity.
