Consider what is worth it to you. A poster mentioned above that they have sold a roll for $15 ($5 over face). It doesn't take much effort, but you still have to communicate and meet up with the people. Ebay is an option, but you have to be honest with photos showing the impairments. If not, the buyer can always claim the listing wasn't accurate and get their money back. Even if the listing is successful with no complaints, you are still dealing with a minimal profit after eBay fees. In most cases, people will say that it isn't worth their time and hassle.
Now, I still pull the nice looking proofs. But I use them for tips. The one waitress profusely thanked me for leaving such a generous tip. (The tip was the same 20%, but in proof halves). I told her it was my pleasure. Now, when I return, I get exceptional service, and likely a level of service that others don't get. That is worth more than any tiny profit margin that I would have received on eBay.
