Opinion of posters here is split. So will your buyers be. It only takes one buyer to have this perception, rightly or wrongly, and you have a neg with a fake claim, and you are stuck with it.

Facts are a second cousin to perception when it comes to sales and marketing.

Reckon lane-ends has hit the nail on the head.

Perception is everything !! 

If you have a doubt, IMO bin it, its what I do.  Its not fair to buyers if a seller can not stand by the stock they sell.
