I knew about pennies since 2006 or earlier, but just started hoarding them 3 weeks ago. I was speending all my money on silver and then I got some Nickels.
Only when i started reading here did I decide to mess with pennies, and there are several "myths" that will keep even the average Silver/gold/ coin hoarder out of copper.
1. Myth 1. There is not many copper pennies left. Lot of people think that the pre zinc pennies are hard to find and they will never get enough to make a difference.
2. Myth 2. The pennies are hard to sort. They believe that it's just going to take too long to sort enough pennies to make a difference.
3. Myth 3. It's going to take up too much room to store all those pennies. The envision a ton of pennies taking up the spare bedroom.
4. Myth 4. They can't be melted, so they will never be worth more than a penny. This one bothers me the most, because 0% silver trades above face value everyday without being melted. A copper penny has intrinsic value equal to the amount of copper in it. It would be like saying a Silver Eagle wouldn't be worth it's silver Value unless you melted it.
It was Andrew Lin's video, that shows how little room a ton of copper takes up, that got me to finally start hoarding.
