i just got a vintage gucci frame clutch with a "G" flap clasp. it's a gorgeous bag, and the seller described it as from the 1970s. it only has a gold "GUCCI" brass plate above the inside pocket though. have you ever seen an authentic vintage gucci bag from the 70s or 80s with just a "GUCCI" gold plate, without any serial #, "made in italy" imprint?
thanks
For issues of authenticity please post pics/link of the bag in the 'Authenticate This' thread as pro form
To answer your question Gucci used model numbers for many but not all bags. These were not serial numbers.
Usually 'brass plates' are associated with the 1980s and not the 1970s. Most 1980s bags do have season/model/colour numbers.
One or two 'rules' do not verify whether a bag is real or fake they are just reassurances and information. Fakes often have similar markings and it takes a good eye and experience to spot differences between.
I hope this helps.
