I think the recycler here has been paying about 50 cents a pound for aluminum; or so I heard. Some parts of the country are probably paying more than that.
You could try listing them on Craigslist (it's free) with a "Make an Offer" notation and see if someone's interested in them. Just notate they're problematic, sold AS IS, and someone may want them at higher than scrap prices even with warts and all.
Personally, I prefer steel wheels any day of the week. Less prone to leaks, damage, and they maintain their balance better IMHO.
