Lucky enough to have a vintage Gucci item in your possession? Perhaps a classic Jackie bag passed along from your super chic grandmother? (Well, a girl can dream.) Find out how much it’s worth now that renowned auction house Christie’s has teamed up with the luxury fashion brand on a new online appraisal service, Gucci Collector. Simply upload photos of your vintage Gucci items, fill out an appraisal form and within 2-4 weeks you will receive an estimate. You will also be notified if your item would be appropriate for upcoming Christie’s vintage sales or if Gucci would be interested in it for the museum they plan to open in Florence next year in celebration of their 90th anniversary. Who knows, you might be sitting on a serious Gucci treasure!
