should i resell or return my new coach???

Are you sure it's authentic? I was looking at the pictures and teh one at the very bottom has only 4 lines of C's and teh other pictures have 5 lines going down the front?

The C's at the bottom don't always line up even on authentic bags.

So I wouldn't rule out the bag is not authentic just yet. Post pics of the creed and ask the seller to take some clear pics. That's the only way to know for sure.
 
I am going to say it is fake. Look at the other 2 listings she has up. She excludes Coach from the title to circumvent the Designer Queu. This is an instruction given on websites to people who buy fake bags to sell on ebay.
 
I'm not sure about the authenticity of your item, but I have a comment about the leather. My 9 1/2 year old's pink optic hobo is trimmed in the vachetta, and she has no issues keeping it clean. You should be fine.
