They still make coin purses, but I'm not sure if the style has changed from whatever you're thinking of for 2004. Balenciaga New York doesn't have its own site, but there's a Balenciaga site in general. Here's the link to the bag section on it. http://balenciaga.com/#Id=/Collection/Women/Accessories/Bags
If you check out the Balenciaga reference library you will find the answers to all of your questions....including a complete list of all the styles currently being produced!
