Hi can anyone help?

I bought a chanel bag in barcelona quite a few years back and now I'm looking to sell it but I can't even remember what I paid for it!! Don't want to sell it for less than its worth but I can't find anything similar on the net to compare it too.

Its a doctors bag with a black leather handle and beige stitching. The body of the bag is felt I think, black with small chanel monograms all over it in beige. Anyone have any idea what its worth or where I could find an archive of pricing/old collections.

Cheers :-)
