My Chanel Bag

ebay- or take it to your local consignment shop- they will usually split the sale 50/50......
try anns fabulous finds- i can not remember exactly how she consigns on line or if she did, or still does
 
I would check if it's real in the first place. Take some more pictures of the interior and post it in the "Authenticate This Chanel" thread before even proceeding to the possible thought of selling it.
