Hoarding Nickels

A US Jefferson Nickel is worth currently about 6 cents, according to this great link (from coinflation.com -- used for calculating the intrinsic value of us coins made from base metal). This does not include productions costs.  Nickels are still very common so you would be making an automatic 20% gain if you decided to start hoarding them, assuming you could melt them, which you can't -- it's currently illegal.   But it does underscore the deteriorating value of the US Dollar.
