Casascious coins had the private key etched in brass. These seem to be able to rotate keys. That way you can be sure the previous owner won't sweep. Similar to opendime in that you have to break it to claim.
iirc, aren't there laws prohibiting the production of something which looks like fiat, but which isnt? Liberty Dollars were shut down for this reason. I thought Casascious was ceased for the same reason. Casascious def wasn't ceased just because it had a static private key.
I'd recommend making these not have a resemblance to domestic or foreign fiat notes.

It is one's duty to violate an unjust law.
Besides, there's an enormous industry of challenge coins and anti-counterfit notes to represent all kinds of things that aren't currency.
Casascious was a long time ago and there's a lot more clarity around BTC now. Currently, no agency recognizes it as a currency.
These notes are akin to a decorative display case for your gold nuggets.

Close. The Casascius coins had a private key underneath a tamper-evident hologram sticker.
This seems more like the OpenDime. Where to redeem it you physically alter it (by cutting the "wire" (trace) so that it then changes state to reveal the private key.
