Since you own a pro shop, and you're apparently talking about more than one ball, I assume you want to sell them.
So, like any other ball you want to sell, there's more to the matter than just how good a ball it is. On the plus side, it's an attractive ball, and since you're not paying much for them, you can price it attractively.
On the negative side, AMF bowling has gone through some rough times, and some people might not be inclined to buy a ball with an AMF logo on it.
You know your customers better than we, so it's really your call. If the price is really "dirt cheap", you probably don't have much to lose.
As a final thought, keep in mind that it's a particle ball, so if your local house doesn't put out much oil, you may have a tough time finding bowlers with enough ball speed to get it down the lane.
