Vintage Gucci Boston Bag

This is my grandmas vintage Gucci from the 70s or 80s. It’s a beautiful bag that hasn’t been used in some time and needs some TLC. The interior is stained from her makeup and the handle is damaged but seems like it would be easily fixable. The fraying on the interior is not visible when the bag is zipped. I wasn’t sure what price to set since it isn’t in perfect condition so offers welcome :)
