I was given this by someone who is quitting and there are absolutely NONE in shop search or trades. Subetalodge says it's from the September 2012 Collection. Is the average of 9mil good enough to use in my shop?

As the September 2012 collection is priced at around 9mill, I think that (or a little less if you want it to sell quickly!) would be an acceptable price for this item. :)
