Value really depends on the quantity purchased. Smaller quantities, 10 cents a piece shipped is a decent price right now. For larger quantities, 5 to 7 cents seems to be market price right now. Of course for in-person sales you can reduce those prices a few cents per piece.

Even used brass has gotten hard to find in a lot of places. It was so plentiful a year ago that most people wouldn't bother to pick it up, even if they reloaded. A lot of those who did, and collected big buckets full, have now sold off about all they are willing to sell.
So now anyone with a bunch of it on hand has something of value. Still not a huge value, but getting more valuable every day.
