Credits

HyperCurio is built on other people’s work: open databases, public records, marketplaces, typefaces and software. This page credits them, with the notices their licences ask for. Naming a source here does not mean it endorses HyperCurio, and every trademark belongs to its owner.

Wikimedia Commons 844 coin photographs

The coins on the U.S. coins checklists are U.S. government money and in the public domain. Their photographs are files on Wikimedia Commons; many are shared under a Creative Commons licence (CC BY or CC BY-SA), named beside each one below with its author where Commons gives one. Where a checklist row has no photograph of that exact coin, we show the same year from another mint, or the series’ design with the year of the coin pictured, and say so. Each picture below links to its Commons page, which names its source and licence. If you hold rights to one of them and would like it removed, tell us through the chat bubble in the app and it goes at once.
