Can coins and papers be stored in the same container such as a small safe without damage occurring? I do use products to reduce humidity. Thanks!

Welcome to Coin Community !!  Shouldn't be a problem. I do the same thing, and I've had no problems. |

I have a bank box and only your unsealed copper coin will tone & some older silver type coins like unsealed 1891 silver dollar from Canada so far and they have been in there 20+ year some of them.Its nice tone not like the rainbow man made toning

Welcome to the forum.
Your statement needs more clarification as to what you mean by papers. If you are referring to paper money, documents such as wills or deeds, newpapers, magazines, bags from a store, etc. You simply stated papers. Some paper products contain chemicals that could effect a coin and some don't. Regardless of the type of paper you are discussing, note the following. Toning, corroding, etc on coins is a chemical reaction with numerous different agents. This can not happen with out the presence of air and moisture. If you keep air and moisture from your coins, then any paper products can not effect your coins.
This can be verified if you go to a museum and look at the mummies from Egypt. No moisture and look how good they still are. Hopefully your coins will also look the same in a few thousand years.

Welcome! I have a safe that holds my coins as well as a few paper documents (deeds, titles, etc..) and have had no problems. I also use silica gel to keep the humidity down. The only problem I have had is when I open and close the safe too much. Once sealed, the silica does it's thing and has to do it over and over whenever humidity is introduced. No big deal, I just have to "recharge" the silica more often than I would like. Now I keep two sealed up and rotate "fresh" ones in when one gets used up. This allows me to bake them all at once to dry them back out. |

just don't allow copper and silver coins to come into contact with each other...chemical reactions will take place and ruin your coins!

It's better to part coins and paper and I agree with atlashealth that copper and silver coins should not come in contact due to the chemical reaction that might cause a negative impact on each other. Anyway, if you keep your coins safe and take the necessary precaution you might later sell them for quite a sum of money.
P.S. Welcome!

Are your coins in holders? Paper is acidic, direct contact of coins and paper is NOT recommended.

Best to have the coins in 2x2s or another form of holder.

Exactly what kind of reactions will take place with ANY two metals?
Exactly how does two metals react with each other chemically?
Exactly what substance would be possible from the combination of any two metals?
Metals mix, not chemically combine.

Actually, metals in contact don't "mix", but they can form a galvanic cell which will cause corrosion.

Sorry just carl, I meant what BadThad said...keep different metals and paper from contact to be on the safe side. especially for long term storage.

Actually, metals in contact don't "mix", but they can form a galvanic cell which will cause corrosion.
This is purely dependant on the reactivity of the metals in quesion. For example there is an electrical current created when disimilar metals of certain types touch each other. However, this is only with cetain metals. This is the principal of an electronic electrode called a thermocouple and only when there is a change in temperature otherwise nothing happens. For example a pair of wires composed of one Chomel and one Alumal is used for monitoring changes in the piping and duct works in both nuclear and fossil power stations. Such a pair of wires is run back to the main control board where a sensitive gauge is used to monitor differences in temperatures of pipes and ducts. Also, some are just placed near a reactor outer containment structure inside a thermal head to monitor changes in ambient temperatures around such structures.
As to metals mixing, true under NORMAL everyday conditions they will not mix together. However, an to form a galvanic cell, again certain conditions are required and jusp placing a Silver coin next to a Gold coin will basically do nothing unless the temperature is modified substantially.
Just an opinion of course from a person that has worked on almost every Nuclear in the area.

just carl  For two different metals to form electrodes causing a galvanic cell, a change in the environment e.g. temperature or humidity must occur. The presence of an electrolyte is essential for the process of corrosion. quote:

This is true, gold and silver when mixed in jewellery affects each other because of their direct contact with our sweat, which contains salts that acts as an electrolyte for electric current to pass through. |
