Condolences on the loss of your father.

If your American swap meets are anything like those in Canada, you'll find that they are not a great place to get a good financial return on the stuff. Everyone there expects to get stuff for nothing.

If you're willing to almost give it away, the advantage is that you will dispose of stuff quickly.

My selling decisions are determined by how much I think the item will get and how quickly I'd like to get rid of it. That determines where it is offered.

ebay is usually a bit slower with generally a higher price.
