I have a 5 gallon bucket that has 3 inches of primers in it. It weighs 10.5 pounds. You won't get rich, but it's better than sending brass to the land fill.
99% of mine go in the trash. The other 1% cause my wife to yell obscenities at me from across the house when she steps on them while walking past the reloading bench.
I kept them in a coffee can just to sort of see how many loads I had loaded since I started. It was sort of cool but when we moved they went in the trash.
