Medals are a form of "exonumia" - objects related to coinage but not coins themselves. such are, for example, the medals included in many Royal Mint proof sets. They do not have any "face value" and are not tokens either, but can still be of interest to coin collectors.
Tokens were used in the past as a sort of privately issued money. This is no longer the case, but mints and other entities now strike medal-like objects they call "tokens".
This medal was part of the Aussie Bubs - Uncirculated Set 2025 released in April 2025, which is part of a long-running series of baby sets released by the Royal Australian Mint.
The set contains "baby versions" of the circulating denomination, and they are all depicted on the medal.
The mint says:
"A fluffy Tawny frogmouth chick nests on the 5c, while a shy Leafy seadragon fry floats on by on the 10c coin. A cute Leatherback turtle hatchling enjoys a day at the beach on the 20c, while an adorable koala joey is ready for a nap on the 50c coin. Rounding up the gang is an adorable quokka joey on the $1, and a naughty Tassie devil joey on the $2 coin." |
