Mass Penny Storage

I have seen cents tone after keeping them in those boxes for a few years, so those aren't recommended.

Best and cheapest, would be to buy plastic cent tubes. They cost about $28 per 100, plus shipping.

But make sure you remove any corroded or nasty ones, otherwise they will contaminate the rest.

If you are talking large quantities, buy come canvas coin bags and bag them in $50 face value bags. That way you'll know how much you have when it's time to sell. Store them in a dry location to prevent corrosion. When you end up selling them it will most likely be to a dealer that has a coin counter and he will count and keep them in those bags for selling. Eventually, copper pennies will be traded just like bags of junk silver coins are. They same can be said for nickels.
