There should be a date code inside. That should help. Celine got really popular when Phoebe Philo became creative director in 2008. Your bag is a bit older than that, I think. That would affect its resale value. Also, please make sure it's authentic before listing it anywhere, just in case. There's a designated thread here on the forums: https://forum.purseblog.com/threads/authenticate-this-celine.884802/Thank you! My mom wants to sell it but the first reseller we contacted didn't know the model and valued it at a really low price. Knowing the model will at least help me find out how much it sells for on the internet.
