Asymptote
Asymptote is a design, architecture and research practice based in New York, and has developed 3DTF, a virtual reality trading floor, as well as a "web environment" for the New York Stock Exchange. These projects are the first large scale VR environment used for business purposes. Unfortunately, the website uses "bleeding edge" technology and is difficult to navigate. To get to the projects from the front page, you must first go through their "digital environment" subpage.

Museums
The British Museum
The British Museum is world-renowned for its numismatic collection (Department of Coins and Medals), containing about a million objects from the 7th century BC through the present. The site features an exhibit, "Brief Lives," on the legacy currencies of Europe - those that are being replaced by the Euro. Beyond that, the site offers background on the collection and research of the museum, but a limited number of images. They do have an extensive bibliography which would make an excellent starting point for research in numismatics.
Museum of American Financial History
This small but well-designed museum located in Manhattan showcases the history of Wall Street and the achievements of American businessmen and women. Their website provides highlights of current and past exhibits as well as choice items from their permanent collection. You can also download financial-themed wallpaper for your computer.
Israeli Finance Ministry, Museum of Taxes
This site has no exhibits online and merely provides information about the museum and their publication, the Israeli Tax Review.
Organizations
The American Monetary Institute
Despite the institutional name, the site appears to be the work of a single individual, Stephen Zarlenga. There are a very small number of resources available for free; most seem dedicated to debunking an exchange theory of money.
