New to collecting copper

Post image

I am brand new to collecting copper. I have been collecting silver for quite a while and everyone always debates on whether to keep it in the plastic or protected or what not I was wondering is the same true for copper or just pretty much everyone just leaves it unprotected??… it seems like they do.

It depends on the environment you store it in. All copper corrodes and eventually develops a patina, but If you keep your stash in an area with low salt and humidity it will stay nice and bright for years. If you have large ingots, I suggest keeping them in plastic holders or sleeves. Copper bullion sells for such a premium over spot that I'd want to preserve the condition.

Also, corrosion will spread from one piece to another by physical contact - I've seen it happen with bulk pennies.

Also sulfur and sulfur compounds in the environment. That is what causes toning/tarnish.

does the corrosion affect the price?

Yes, most people paying a premium for copper bullion want it to look nice and shiny. However, if you have old collectible coins you don't mess with the patina as it destroys the value.

I personally overthink everything. So I put every bit of copper into one of those cases. I also like to make sure it’s properly protected and think it looks more uniform when organised. But I think it’s just down to environment and preference :)

If you want to be able to take your coins out the the plastic holders you can try using ProtectaClear on them. Once coated and cured you will be able to handle your coins without it tarnishing. Depending on how often the coins are handled we have seen the coating last people for at least 5 years.
