Bless you. I know farming n ranching hard work and feed prices have gone balistic. But, the knowledge, skills and experience you've acquired will be worth more than metals. Having said that, saving pennies and nickels will also payoff. Check out coinflation.com. You will find '82 pennies n earlier worth ~2.5 times face value; nickels just over face value; and > '82 pennies (zinc) approacing face value. Base metal prices expected to rise significantly.

Wrap 'em, stack 'em, and forget about 'em. I use ammo cans to store the wrapped coins.
