Your Storage Method?!

So all acetones are not created equal? Regular acetone will harm coins?

Just a rookie here..

Peace

Well, the whole reason for my thread was to find a way to keep my coins safe and still be able to look at them at will. I believe BadThads routine is perfect for me. I definitely will not be putting these away and forgetting about them. I can sleep better at night now knowing that my coins are safer then the day before, protecting my investment etc. I hope this clarifies my reasoning anyways ;)

I'd also like to hear from BT about the acetone question, I have been using just your typical off the shelve stuff and hope it didnt hurt anything.

Well, I don't think cheap acetone will damage your coins, but I've never used it. One ingredient in finger nail polish remover (primarily acetone) is ethyl acetate and perhaps some trace acetate radicals. Free acetate is anionic and may bond to the metal surace (residue). Ethyl acetate is also volatile so it should evaporate, but not as volatile as acetone. My larger concern is residue due to impurities and acetate in the cheap stuff.

ACS (American Chemical Society) grade acetone is fairly cheap and brings a nice piece of mind....espcially when being used on proof coins.

That acetone looks pretty good, it claims 100% pure. Did you do a residue test? Pour out about 50 mL of it into a glass container and allow to evaportate, check for any residue.

My main concern with acetone is the type sold in those little plastic bottles, it's usually impure.

From my years as a chemistry teacher, reagent grade should work fine. You don't want "technical" grade. There is a purer grade beyond reagent. I think, and I may be remembering wrong, it is USP grade

The cost is pretty much geometrical going up the grade ladder. The purer you require, the more it costs.

Sorry, forgot about this. I found no residue with my tests.

Hi everyone! I am new to the forum, but it looks great. Hope you dont mind my input on the subject. I have been trying to find or make my own "ultimate" album for years now. First I used the dansco albums, but found coins began to tone quite fast. Then I put new coins in "kointains" the into custom size pages to fit the size of the coin in the kointain (about 2mm larger than normal). That was better, but not by much. I then tried storing them in the kointains, in "Gardmaster" pages. This seems to work very well. Only problem is I was getting spots on the sides of alot of the coins, I think from the kointains. I talked with them, they said not possible from their product. I then decided to put them in direct-fit "Air-Tites" this seems to be perfect, but they no longer fit the Gardmaster pages very well, due to the thickness of the capsule. I have been tring out a few different 2x2 holders, like BT has done and thinking of storing that way as well. Bye the way I have been rinsing all my coins with acetone for over 15 years and all look as new as the day they were minted. I will try to post pics of my "methods" of storing during the week to see what you think.

crusherjc!

Interesting path you taken to get to Airtites. A quick acetone rinse, then into an Airtite will serve you well for many years! I was sad to see a price increase at Valley coin for Airtites last night when I went to order more. They have gone from 0.39 to 0.47 each in bulk.



Nonetheless, I think they are the best and most economical way to store your coins.
