If you have a Business Platinum card the points are worth $0.02 as explained in the Wikipost at the top of this thread:

Otherwise the highest monetary value comes from transferring to a frequent flyer program and redeeming for intercontinental business class flights. $0.02 should be achievable without a transfer bonus, but of course it doesn't matter if you are not interesting in that type or style of travel.
