Just like it says on the tin: half a bitcoin, silver, 2013.
I'll be up front with you: I don't know anything about bitcoin or, specifically, this coin. I got the coin from a crypto enthusiast, but I never got into crypto myself.
I know it's worth half a bitcoin at a floor, and an auction seems like the best way to find the ceiling. 😎
Is it series 2 or series 3? I don't know. You'd think this would be easy to find out; it's not. The pictures are not helpful, and the wiki doesn't list the differences comprehensively.
Chain of custody? Couldn't tell you. It is currently mine and that's ~as far back as I can trace custody (gonna leave the previous owner out of this).
Grade? Uuuhhhhh look at it. As far as I know, it's never -- not one single time -- been in a protective case, and I can tell you for a fact that it's been touched by ungloved human hands. I am touching it while I write this post.
If you've got fun facts about Bitcoin, this Casascius dude, or collectors' coins, I'm all ears. 🦻
Here's pictures:

Here's "verification" that it's still loaded (I don't know how reliable this site, maybe you do):
