Kennedy Half Dollars for HanDBase - Manage your Kennedy Half Dollar collection. I have different databases for different types of coins. All databases are essentially the same, just named different. I place each database in a coorsponding Category. For example, I have all Dollar databases under the Dollars Category. Used with categories, the design is very similar to another palm based database for coin collectors available on the Internet. Feel free to use the database as a template to add other coin types--but if you do, please share.
