Tyrant Gears sold in shops????

I stumbled across this when I was leveling my BaM (in gMS) and had to stop to ask about it because so many questions:
Does anyone know where we get the Maple Magus Coins?
Are they out yet? (I couldn't find any info in the extractions)
...Or do you think that they'll be a boss drop when Black Mage is eventually released?



The three pieces for every class, (boots cape and belt) are sold at this vendor.
