This bag is completely made of a solid brown leather. There are only 4 digits at the end of the serial number and the stiching on the purse is perfection. It has what I believe is brass hardware, but I'm not completely familiar with metal hardware. It's a crossbody style with a flap that comes over the front with a strap that has an attached belt buckle to keep the purse closed and secure and a little magnet with "coach " engraved in it. It has a little wear at the base of the bag due to normal wear, but the rest of it is beautiful. The interior is lined with what I assume is silk. The lining is brown with "coach" stitched in a very precise pattern. I haven't been able to find this purse anywhere on the Internet and I would like to know if this handbag is genuine or just a replica. Any info or resources would be greatly appreciated.
