they are hard to see in vendor backpacks against almost any color container background (ugh), so they sell BAD in luna even though they're very uncommon. since they're equippable you should have no problem getting 75m, but if i were you i'd try to sell it at auction. post a screenie and show it equippable, that helps

i learned the hard way- i bought some to resell and it took forever =P
TL;DR - for the hell of it, i'll offer 40m !
