I think $0.005 is reasonable since that's what I'd get if I immediately cashed out to Amex gift cards which is the closest cash equivalent.

I'll report back here if the IRS fights it, but I highly doubt it. If Amex values their own points at $0.005 for their own gift cards, that's as strong a case as it gets.
