This really hasent been a problem until now as i have stored all my currency,bullion And guns plus other valuables in either a safe deposit box or in a secure cabinet in my den. so i decided to complicate matters and go out any buy a 1,200 pound gun safe, this things is huge...LOL, but the problem is its just to big to put anywhere in The house, my den is upstairs so for obvious reasons not a good choice. So i have in a great place in the garage, however its hotter then you know what in there with temps in the 105-110 range most of the summer and would say add atleast 5-10 degrees to that, i am a little bit concerned about possible affects to the notes, its very Dry here with humidity levels of only 7-10% so moisture levels are not a problem. But i do have several one of a kind notes that are worth several thousand dollars and would rather have them close by to enjoy then setting in some safe deposit box gathering dust. Would really like to hear from anybody else that is dealing with a similar issue.
