My mum has recently moved into a care home and I've been sorting through her clothes. She has a vintage Cartier headscarf in the Cartier box with a certificate of authenticity. I guess it's maybe from the 70s or 80s. I suspect it's never been worn. It looks in pristine condition.
I've had a quick Google and can see they sell online for quite large sums of money. Any ideas how I could get it valued or who I could sell it to or through?
