See a quarter of a million objects at a museum about money
250,000 objects, all currency
The public museum of the American Numismatic Association, established 1967, holding roughly a quarter of a million objects relating to money.
Why it's unique
The Edward C. Rochette Money Museum at the American Numismatic Association is the largest museum in the United States devoted to money, holding around 250,000 artefacts across three galleries: coins, paper currency, tokens, medals and traditional money from cultures that never used either.
The scale is the claim, and it is corroborated by American Heritage independently of the ANA, which matters because the association is also the source of it. What the size buys is depth rather than breadth: this is a research collection with a public front, not a themed gallery about the history of trade.
Before you go
The name undersells it. People assume from the wording that this is a small society display rather than a 250,000-object collection, and skip it.
The rarities are concentrated rather than spread through the galleries, and what is on show rotates, so ask at the desk which of them are currently out rather than hunting. It sits on the edge of the Colorado College campus rather than downtown, and it is closed some weekdays.
