1970’s vintage coach tote bag, laptop work bag

Cognac tote by coach. Based on the serial numbers pattern xxx-xxxx and it being ‘made in the United states’ this bag is mid to late 1970s. It does have signs of wear but for being 55 years old is in FANTASTIC USED CONDITION. Please see corners pics and pictures of the discolorations on this bag. I have not tried to clean or co diction this bag.
