Edmund Halley's coin, also known as Halley's Comet coin, refers to a coin minted in 1710 to commemorate Halley's prediction of the comet's return. The coin features an image of Halley's Comet and is considered a collector's item today. Its value can vary significantly based on its condition, rarity, and demand among numismatists, but it is generally worth several hundred to a few thousand dollars. For an accurate valuation, consulting a numismatic expert or auction listings is recommended.

Edmund Halley did not invent anything, but he was a British astronomer known for calculating the orbit of the comet that now bears his name. Halley's Comet, which passes by Earth approximately every 75-76 years, was the first comet to be recognized as periodic.
