Conserving aluminum coins?

[Star City Homer]

I tried a search and came up with nothing, so I ask....

 

I have noticed many aluminum coins can aquire a bit of haze (even in the mint packaging). Is this somethin NCS can conserve?

 

Thanks for any info.

 

 

 

edited to add: I'm talking darkside here

Aluminum is tricky. I have a bunch of aluminum coins (obviously, dark side as well.) Just don't try acetone on them, I made that mistake on one coin and it ruined it.

Aluminum is tricky.

Exactly!

 

 

I've gotten a (relatively) couple of nice/rare-yet-not-too-expensive ones now that are a little hazed out with what I presume is oxidation.

 

I'd like to submit them, but I have no idea what, if anything, can be done to stabilze (or fix) them.

 

I don't mess with anything at all, and I would be most scared of aluminum. That's why I'd like to send to NCS, but not if it's a waste of time.

My understanding is that aluminum oxide naturally occurs in air - there is nothing that can be done for it.

Put it in an Airtite so air can no longer get to the surface.
