Australian Dodecagonal 50 Cent Coin

The item is an Australian 50 cent coin, identifiable by its distinctive dodecagonal (12-sided) shape and the visible reverse design. The coin appears to be made of a silver-colored cupro-nickel alloy, typical for this denomination. The visible side prominently features the Commonwealth Coat of Arms, which includes a shield held by a kangaroo and an emu, surmounted by the Commonwealth Star. Below the shield, the denomination '50' is clearly visible in large numerals. The surface of the coin shows signs of circulation, indicated by a slightly dull finish and some minor surface wear consistent with handling over time. There are no immediate signs of severe damage such as deep scratches, major dings, or corrosion, suggesting a generally good but circulated condition. The craftsmanship appears to be standard for a circulating Australian coin, with clear details on the coat of arms, though some of the finer lines in the shield might be slightly softened by wear. Without seeing the obverse, it's not possible to determine the exact year, but the design visible is consistent with 50 cent coins minted from 1969 onwards, following the initial round 50 cent coin. The dodecagonal shape itself is a notable feature, making it easily distinguishable from other denominations or coins from other countries. The edges appear intact, maintaining the multi-sided polygon shape.
