Zittergie's Coin Catalog for Mac

From Zittergie:

Zittergie's Coin Catalog is a software catalog and Manager for coins that runs on Linux, Windows and MAC OS 10.5 It is meant to be used on portable devices, so it is optimized for really small notebooks like the ASUS EEE PC, but it runs just as good on bigger resolutions too.

It's Multi-Lingual (Dutch, English, French, German, ...), it's Multi-Regions (All regions/countries can be used as a catalog), it's Multi-Purpose (Not only it's a catalog, you can keep track of your own collection).

You get a quick overview of all of the different coins from one country, value for different grades, mintage, variations, metal, weight, edge, diameter, pictures. Look up coins on www.zittergie.be and www.ebay.com.
