Do you ever have trouble telling them apart? The newest Box I have is a Birkin bought at store in 2001. It is so shiny that it makes some of my older Box look like Chamonix. I keep hoping this Birkin will lose this patent leather- like shine, but beside other Box, it seems too shiny. Bought a black Box piece yesterday, at least SA said it is is Box. It is not marked on tag and it looks like Chamonix to me.
