I know there is a website, or maybe just a program, that will calculate the value of your games by cross-referencing your BGG library with the average price paid on the BGG marketplace. I'm sorry I can't remember the link, so that's not very helpful, but perhaps someone can find it if they look hard enough. I'm not sure if it's possible to see the breakdown, but if so, you could simply add up all your Carcassonne stuff.
