Have any of you had experience, good or bad, with Nimbus frames that "suspend" coins between two sheets of silicon? I'd be especially interested in long-term effects, real or possible. Thanks, Steve
I had to google. Didn't understand what you were referring to... They don't seem completely airtight so maybe toning would be an issue. What coins and why would you want to suspend them? Decoration for an office wall?
Their web site says "coins should be inserted in capsules." That sounds to me like there's stuff in there you don't want near your coins.
I was thinking a nice BU set of war nickels would like great instead of placing them in a Capitol or similar holder. I thought it might look nice on the wall of my home office and IF they were stolen it wouldn't be the end of the world. I missed the advisory of using something to enclose the coins; the use of Airtites might defeat the esthetics though. Thanks for your posts. Steve
These frames are two clear silicone sheets held together by friction (mine has a magnetic flap that holds the two sides opposite the hinge). Silicone is very, very inert - it's used for medical devices and cooking (even to high temperatures). The reason for using capsules is that the coins can slide, especially if there is more than one in the frame - because of the stretch of the sheets. I had thought to have a 'pile' of coins representing a gentleman's pocket contents, but there just isn't enough pressure to hold them without movement.
So, Burton, do the capsules prevent sliding for you? How many in your frame? Would you recommend a larger frame for 11 war nickels so the silicone has more space to cling to itself? Steve
I can't really guess how well 11 capsules will sit. It won't work for me - a typical "gentleman's pocket" would be 44 cents - a SL quarter, dime and half dime, an Indian Head cent and a 3 cent silver. And I wanted them to look like "a pile" on the dresser, so in the smallest frame and with non-uniform thickness - they slide.
