My sister and I are cleaning out my Mum's jewelry, shoes and handbag collection and she has a ton of Michael Kors handbags. Can anyone tell me when Michael Kors started using the Jacquard Signature Logo print and when that print was discontinued? My Mum can no longer remember when these bags were purchased and insists all the bags are brand new. We are trying to determine a resale value for the handbag collection prior to contacting professional resellers. Thanks so much.
