Since the NES sold like a gazillion units back in the 80s, it makes perfect sense to have even more controllers lying around, waiting to be recycled (or suffer a different fate). For those with a penchant for DIY items, why not turn this into a coin purse as depicted here? The NES controller has also been lined with an adorable looking fabric. You should be able to find plenty of such NES controllers on eBay before you embark on this project. Would be nice to see this compartmentalized inside to store DS cards instead.
