Australian Decimal Coinage Appraisal

Australian 20-Cent Coin (Reverse Side)

The item is a circulating Australian 20-cent coin, displayed showing its reverse side. The coin is circular in shape, with a reeded edge, though the edge is not fully visible in the provided image. Its material appears to be cupro-nickel, giving it a characteristic silver-grey metallic color. The design on the visible reverse side features a platypus (Ornithorhynchus anatinus) swimming in water. The aquatic mammal is depicted facing right, with ripples in the water around it, indicating movement. The numeral '20' is prominently displayed to the lower right of the platypus, denoting its denomination. The word 'CENTS' is not clearly visible but is typically present below the numeral on this design. The coin exhibits signs of general circulation wear, including some loss of crispness in the details of the platypus and its surroundings, as well as a slight dulling of the metallic luster. There are no obvious deep scratches, dents, or significant damage, suggesting it is in good, used condition. The overall patina is consistent with a coin that has been in circulation for some time. There are no visible maker's marks or signatures on this side, as these are usually found on the obverse (head) side of the coin. The design of the platypus was created by Stuart Devlin and has been in use since decimalization in 1966. Therefore, the coin's estimated age could range from 1966 to the present day. The craftsmanship is typical of Australian coinage, with a well-struck design, maintaining a good level of detail despite circulation wear. The unique aspect of this specific coin is its iconic Australian wildlife representation, making it instantly recognizable as Australian currency.
