fmtaxguy Valued Member United States 257 Posts	Posted 06/06/2009 3:50 pm I am looking for a small amount of reusable desiccant for a smallish home safe, but can only find them in aluminum canisters. What I would like to know is if any of the various coin metals would react adversely to being in close proximity with aluminum. Your experience with this would be most appreciated.

fmtaxguy Valued Member United States 257 Posts	Posted 06/06/2009 11:15 pm Thank you. I saw the Air-Tites site. The small packets would be fine, except they are not reusable. The smallest reusable comes in an aluminum canister. So, the question remains: would the aluminum affect any of the coin metals merely by being enclosed in the same small safe? Thanks in advance.

Actual contact could cause contact corrosion over a very prolonged period. Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis Report this Post to the Staff
John1 Moderator United States 56855 Posts	Posted 06/07/2009 08:03 am I bought one many years ago that is reusable and it is in a glass container with an aluminum top, so maybe they still make them? John1 Report this Post to the Staff

fmtaxguy Valued Member United States 257 Posts	Posted 06/07/2009 10:17 pm Thanks John1. The plastic casing serves to ease my apprehensions, and the $7.50 price isn't bad. However,the $10.50 shipping loses my business. Perhaps I can find that one other sites with reasonable shipping. But I appreciate the link. Report this Post to the Staff
John1 Moderator United States 56855 Posts	Posted 06/08/2009 10:05 am Remember some plastics are not good for coins so check into that too before buying,the same goes for the ones made from cardboard. All of those will out gas chemicals that might negatively effect coins. I suggest you try your best to find one where the canister is made of glass. John1 Report this Post to the Staff
