Saving Copper Pennies as an Investment

HerWell, as of right now, it is illegal to melt any pennies. A pennies still worth only a penny if it can't be melt. The only usage of copper right now is for thermo and electrical conduction because of it is cheap. In the future, I expect demand of copper will drop. Something with much better electrical conduction is already available. In 10-15 years,the manufacturing process would replace copper in electronics and electrical applications.e is my copper hoard. Copper is around $4.30 a pound which makes a copper cent worth almost three times its face value.
