I'm listing oddball things on eBay right now--I thought I'd try the approach of "this is in my way, it is intended for eBay, why not just list it?" Not the most efficient method, and I need to put some more substantial stuff out, but it has been interesting. Money from the t-shirts goes to my daughter.
Kat, did you get a screen telling you that there are strict rules about posting political memorabilia when you posted those rally passes? I just put up an auction for a 1920s Theodore Roosevelt lapel pin, one of a gazillion left over from a fundraising effort. The park rangers used to just give them away--I don't know if they still do, but I picked up a few 30 years ago. I thought I'd unload a couple, but that is a pretty intimidating message from eBay.
