i mean, you guys must have come across some pennies with those green copper oxide on the surfces; how do you store them? together with the other normal copper pennies, separately, or just return them to the banks? if i store them together with the other pennies, would they "infect" the good ones?
thank you for any input

As long as I can read what year it is, I don't care what color they are or how nasty they are...they all get rolled together.

This probably doesn't make a whole lot of sense, but I admit when I find a penny that is covered in that green crap (verdigris?) I throw it into the zinc pile and return it to the bank.
I don't usually care about condition at all, like imperial said, if I can read the date I keep it. I just really don't like that green stuff. I don't know if it spreads or not, but that is the reason I don't keep them. I plan on keeping my copper cents for years, I don't really want jars full of green crud.
That is just me though, it probably doesn't matter.

If I had to guess, as long as the humidity level is moderated where you store you copper, the green shouldn't spread. I think it may be oxidation caused by high humidity, so if that is correct then storing in a dry environment (<40% RH) should prevent further damage.

RealCent, i have a similar atitude towards those green cents; i save the "not so bad" ones though
ImperialFleet, i put all my pennies in bottles or containers which i have cleaned and air dried for a long period of time to ensure dryness; and once the container is full, i owuld close them with a cap which works as a screw

That is basically how I store my copper cents. I have a bunch of the big old glass table wine jugs that I cleaned out real well and left to dry years ago. I have a bunch filled up and put the screw cap back on and have them hidden. I put little labels on them with something like "US copper cents 1959-1981 $65.00 face value" just in case I never sell or trade them and some future relative finds them after I die. I still have 3 more empty jugs to fill, so once they are full I am going to have to find something else to use...or start drinking wine!

| On the subject of copper cents covered with verdigris (green crud): if you throw them into a container with a little white vinegar, you can watch as the stuff floats off, leaving a relatively clean coin with the green stuff settled out on the bottom. |

very good info., centavito, thank you;
but i suppose the penny would be lighter than the normal ones due to the wash off? |

RealCent, i am using those 2-L pop drink plastic bottles right now; i also have a very stylish plastic barrel people use to store their olives, they are fun to roll around on your carpet
for those 2-L pop drink ontainer, i had one now that's half full, already weighing 4200+ grams, so, if it's full, it could weigh at least 18 pounds, so you need only 6 of those to exceed 100 pounds

If green pennies did spread their disease, you should see multiple green pennies together in a roll and I typically don't see that.
I will wash them off and if I can read the date they go into the appropriate sorting, otherwise it's considered a zinc. |

Re Green copper pennies, there are at least three types of oxidation I have experienced: 1. copper oxide turns the older coins dark. The oxide itself is actually black. Malachite is a blue-green oxidation product worth googling and reading about. To see pennies turn completely green in 24 hours set then on a paper towell soaked in vinegar. This green oxidation product is copper acetate.
Oxidation is neither a disease or infectious but it may seem so, since the conditions which cause it may cause many neighboring coins to turn color at the same time. |

A little off topic for a thread that hasn't had any replies for months but I happened to browse here and though I'd add one thought.
Some people consider copper turning greenish good and intend for that to happen. The Statue of Liberty is made of copper, the artist intended for it to turn the color everyone is familiar with. Don't know how many years it took but it would've been brown or orange or well...copper color like you expect to see copper when it was first constructed (unless shipping the pieces from France on boats across a saltwater ocean already turned the copper greenish). I know Eifel did the internal steel strucure for it, I doubt he was the artist though, can't remember. |
