Hi, I was wondering if someone could tell me if this is an authentic Chanel bag. It measures 12" wide, 11" high, by 4-1/2" deep. I bought it at an upscale resale shop. It is a used bag, not sold as new, but in excellent condition. I'm a little worried about the CC logo on the bottom of the bag; the CC stitching is not complete as shown in the photos. The interior is black leather, with a small zipper pocket which is vinyl. It is in excellent condition. Any ideas as to its age, initial value, or current value? Thanks for any info.
