Re: my physical Bitcoin in aluminum manufactured in a CNC Machining Center
Aw yeah! 
Given that the 3d model is quite complicated, I wonder, did you design the model yourself, or had someone else do it?
That makes sense. Sheet metal is not cheap, and it's usually machined in rectangles (from my experience) - but since this is truly a 3D item, I guess you needed to look hard for a place that deals with large blocks of aluminum. By the way - what are they doing when they are not manufacturing exotics like this?

The cost of one of these is per machine hour, it costs about 50 dollars per hour, the piece in total took about 7 to 8 hours. It really is a unique and very exclusive item.

the model is a coin design that is widely used. MJM did this design and many have used it. this one has some changes though with adding of the forum and forum account name and the difference of text in the box on the back.
I have used the same design to 3d print similar looking rounds.
