Aluminum is a valuable metal that can be sold back into the economy, even in the form of scrap. Currently, scrap aluminum cans are selling at a little over .60 cents a pound. The Amount the person recycling can receive is usually .20 below the trading price.
Aluminum Can Price Formula. Now, there is a mathematical way to roughly determine around how much you are able to receive for your cans. With an average can weighing about 14-15 grams or .03 pounds, an average aluminum can is worth about 2.5 cents at 85 cents a pound.

You need quite a few of these to take your spouse out to dinner.
