I'm guessing Jewelia because Guild Ecks :P
Not sure SC 14.
SC 15 = 80~100Mil
SC 16 = 300~350Mil
If you're selling, I suggest starting at 100Mil and 350Mil for them. Most likely, someone might buy. If you're buying, you MIGHT be lucky to find some cheaper if you wait. :P
+Rep for me if I helped. Thank You!
