Remember what happened with the foam inserts on the Casascius St. Pete coins?
Was it the foam that was the issue for sure? You can always reach out to air-tites.com to see if they have anything available. They are my favorite coins/bar/note case provider overall.
Was not actually "foam"... was a medium-soft plastic insert that was inside a rectangular capsule.
I will see if I can find one or a pic of one....
EDIT: To confirm that they came in those capsules:

"Once you remove the plastic bubble wrapping, you are presented with a see through plastic case, inside of which is the coin itself. I would recommend not opening the plastic case itself in order to protect the coin from any damage. For those of you unaware, (collectible) coins are prone to damage if they are taken out of their protective casing. As this coin will not be loaded with Bitcoin (simply because it isn’t intended to be loaded), there is no real reason to take it out of the casing in the first place."
