On the following Australian coin the Australian continent is on the top while under it the comet is visible.

In Australia was struck the medal that displays Halley's portrait on its obverse, while the comet lying over the MacDonnell Ranges, in the middle of Australia on the reverse. The legend of the obverse of this spectacular copper-colored coin's is "HALLEY'S COMET DOLLAR" and "LIMITED EDITION". The latter suggests that only a small amount of this medal was minted (although the numbers of actually issued is unknown). Right to the portrait is name, birth and death dates. On the left side over the shoulder the engraver's name is visible: STOKES. The reverse side reads: "ALICE SPRINGS N. T." refers to the nearby big city.

Queen Elizabeth's II portrait adorns the reverse of the commemorative 50 pence coin, which was issued on the island of St. Helena in 2002. While the reverse commemorates the 500-th anniversary of discovery of the island the obverse shows Halley's travel to the island in 1676. During this trip Halley has established an observatory and set up a telescope on the island, to study the southern sky. On the right of the medal Halley's half-left portrait is shown. Three-masted sailing ship in the middle, above the comet, the Southern Cross and other stars are displayed. As a legend his name and date of travel was engraved on the medal. On the right side of Halley's coat is a small fish, perhaps the engraver's mark.
The so-called geocoins - which are accessories of a new kind of technical hobby, geocaching - cover a wide range of topics.

The unique identification number on the bottom is used for monitoring the way of that very coin through the world, according to the rules of geocaching. The reverse shows was well-known icon of the International Year of Astronomy.
When the observatory was commissioned in 1974, it was the third-largest telescope of the world, the largest under the southern sky.
