Save them for the winter when you put on a few extra pounds from not being able to ride as much.
I think reselling anything that has been next to your plumbing should be against the law. It's a health hazard. Tide says that their detergent removes 99.9% of bacteria during the wash. Let's dissect that. Let's conservatively say you deposit 1 billion bacteria on your bibs during a ride in the form of sweat, urine and turd. After washing them, there are still 1,000,000 nasties on there. If you think 1 billion is too high, let's say 100,000,000. Still 100,000 remain. In other words, they are not clean and they never will be unless you wash them in bleach which will kill the bacteria and your bibs.
