You're bag was released in 2012 and it is called the Legacy Leather Medium Candace Carryall, style number 19890. I know that it came is a few red shades, including a dark Cherry Red. The bag in the picture below is in an orangish red shade called Carnelian.
I am not an authenticator but I don't see any problems with your bag and it seems to be authentic. It appears that your bag is missing the decorative tassels and the hangtag but you can get a free silver metal hangtag from
Coach Customer Service as mentioned. Call them soon because sometimes is takes awhile for it to arrive - but it is genuine and free!
You could try to find replacement tassels on ebay but I wouldn't bother because it would be hard to make sure that you are getting the same shade of red. You can always decorate the bag with a pretty charm if you wish. Or you could look for tassels in a contrasting color, like navy or black, that would look nice and no need to worry about matching.
I think moisturizing is good but I would try giving it a bath first because it is a grubby and misshapen, but it is a beautiful bag and it has a lot of potential - and it only cost $30!
