The numbers are: 172, 212, and 296.

There were originally 300 released, but only 142 were bought. The user Zegit owns more than 130 of them, most are located in his Mystic Bank Game room, and he has a few in his hand. That means there are less than 12 available to the public at the moment, if I was to take a guess.
