He and I collaborated on these to accomplish these without them being funded. Mike came up with the zero btc holo and the upside down and red dot variants. I have never seen any others pop up that did not match the numbers I have on these and the other limited bars I had.
I can confirm out of the 4- 2FA 100 btc ones, the ending numbers on the holos end with: 40,24,69,55, and that all were sold/traded.
I believe this corresponds with both holos shown.
I can also confirm the value/selling price on these definitely exceeded the offers on the thread.
This matches
There are 17 bar of 100 BTC in circulation ... I have read this infirmation and photo here:

There remains 17 funded, version one, 100 BTC bars.
There are a larger number of version two bars.
This offering is not funded, it represents a different, limited offering Mike did. I am pretty sure the mintage is much higher than four, that is just how many we know about.
I shifted focus a few years back to acquiring the most limited mintage pieces. My long-term view is that if the collectible community fails, it won't matter what the specific investments are. If the collectible community takes off, we will have more collectors, and the goal of completing sets will apply the most pressure to those pieces with the most limited mintage.
To that end, something like this is a neat buy, But only as a longer term speculative investment with potentially a complete loss, and also potentially a multiple-fold gain.
