Nickel rolls have 40 nickels each - $2. Nickel boxes have 50 rolls - $100. A nickel box weighs about 20 pounds, so I once used one to win a "who has the heaviest backpack" pissing contest.
You may actually want to consider saving all pre-1982 nickels, as they're made of 99.99% nickel and are worth about 7 cents each. If you're lucky, you'll find a local buyer.
