Here you go folks. Guaranteed way to make 25% ROI every day. All you have to do is go to the bank and buy rolls of nickels The melt value of a nickle is just over 6.26 cents per nickel If you want 132% ROI and dont mind doing a little work, you can sort your pennies. Anything pre-1982 is worth 2.3 cents For every metric ton of nickels you buy from the bank and then melt down and sell, you make $9300 http://www.coinflation.com/
You might want to price in the cost of leasing a refinery. Then consider the fact that melting down U.S. coins is illegal.
Actually, its only illegal to melt it down on a large scale. Havent you ever seen those machines that flatten pennies and make a design on them. Those are not illegal. Of course melting 1 metric ton of nickles would probably be considered a large scale. But melting down like 100$ of nickels probably wouldnt be.
This could be done as a business outside US territory(if that is still illegal, then by non-US citizens). The problem is transportation of coins, maybe a small factory located in the Mexico border could be an idea
First of all, it is illegal to melt down U.S. currency, period Second of all, if you were to do it, where would you do it and how would you do it? Third of all, why would you melt down nickels instead of 1982 & prior pennies?
