I love the look of floating frames, especially when the coin isn’t in an airtite. However I was a bit worried that the membrane might damage the coin or hologram. So I picked out a sacrificial coin, took it out of it’s airtite and into a floating frame.
This was over 2 years ago. The coin has been on display my desk since.
The results have been great, there has been no noticeable change in either the coin or hologram. The coin is a Ravenbit Node, which is brass, the results might be different with different materials (eg. Silver), but the holograms do not appear to be effected at all.
While the results have been positive I will still probably keep most of my coins in airtites while in the floating frames, better safe than sorry.
Does anyone else use these frames and have you experienced any problems?
