2024 Missing Counterstamp Australia in Space Dollar
As it has for many years, in 2024 the Royal Australian Mint produced a non-circulating one dollar coin that was available to counter-stamp and purchase at various locations throughout Australia, including at the Royal Australian Mint itself. In 2024 the one dollar coin's design commemorated Australia in Space. The coins were struck at the Royal Australian Mint and counter-stamped on location.
Although all coins are meant to be counter-stamped, an occasional few are accidentally sold with no counter-stamp. At least one such coin exists for 2024 and was sold by Drake Sterling in 2025, though it is not clear where it was initially sold without the counter-stamp. There are estimated to be around 12 examples (Eigner, https://www.drakesterling.com/coins-for-sale/decimal-coins/one-dollar/australia-2024-in-space-one-dollar-pcgs-ms67-49993002)
