Stacking Copper Pennies
Collecting pre-1982 pennies can be a hobby that also serves as an investment in copper. The higher copper content in these pennies makes them more valuable as a commodity than their face value and post-1982 counterparts.
The intrinsic value of the metal does not change the fact that thee coins are legal tender. Just like Pre-1965 junk silver, there are many advantages to having an easily recognizable coin rather than some melted scrap copper ingots.
