I've sold .40 brass locally to other reloaders for $.03 each. so 1000 is only $30 but I put it towards what ever project I'm saving for. Every couple months I get it all cleaned and sorted and sell it on C-list locally. Usually goes in a few days and I get some cash. If its rare and I only have a few, like rifle 270 rounds, I found 5 of them. I just gave it to a buddy at work that reloaded 270. He was surprised, He's never seen 270 range brass. If you have a steady in flow of brass, you could put together a decent nest egg for whatever you want.
Hint for counting: get a scale and weigh count, much better than counting to 1000 a few times. It look me longer to type this last time than it takes me to weigh count 1000 or so rounds.
