"Swaglist" typed with or without a space has barely any search volume (something like 22 per month, globally). You'd have to develop it into a brand of some sort if you want it to be worth anything.
I'd immediately interpret "swag" as either apperance or style. Perhaps swaglist could be a site for fashion styles or a list of the latest 'swag' trends...with pictures, etc.
Good example of a developed site with "swag": swagbucks.com...
I'd say high $XX to very low $XXX at best.
