You mean the Casascius coins? Lots of those still out there unswept, they are legit.
They're legit and always will be. There are few others that sure as shit are not and were emptied.
I've always found it really weird the hall pass people gave physical coin creators when it came to the handling of private keys. They're just another anon prick. Just because they're gluing a private key to a lump of metal does not mean it magically spirits away their dodgy as fuck tendencies.
To own a Casascius Bitcoin, you have to have full faith and trust in the word and past process of one person - Mike Caldwell.
I own one, and I fully understand that it's value is entirely contingent on having trusted Mike Caldwell's past process. The fact that he no longer sells them is a bonus.
I would never trust anyone else's physical bitcoin or any other physical hologram coin for that matter. Like ever.
