I could explain what this is, but I think it'd be more fitting if
Casascius did (excerpt taken directly from email):
"I don’t think I’ll end up doing more 5 blanks, as I (to my surprise) am finding that people still want 5BTC coins. I have no idea why. But I think I will end up making hologrammed coins out of my remaining stock and then that’s it. So your blanks indeed will be relatively rare. I think I may have shipped out less than 1000 total blanks."You might think that you can turn a 5BTC coin into one of these "blanks" by just getting all remnants of the hologram off. But, whatever you do, someone (maybe a trained eye) will notice its a "circulated" coin. An original blank (like this) is obviously not circulated, and so it looks perfect on BOTH sides-(see pictures). And the overarching thing - if Casascius made it and confirms it is real-it is just that ; )
So, realize what it truly is you're buying!
*Case is included. This round has only been handled by gloved hands.*
I'm not putting a price on it. Please either post or PM me your offers. If I see one I like, I'll take it. Otherwise, I'm keeping it.
This is my last one!
