Current and very accurate ranges come in short and simple list:
Wreath 7.8-8.8
Bsh 17.75-19
Yellow 28.5-31
Green 32-35
Purple 33-36
Red 39-44
White 50-54
Blue 59-68
Everyone should know that there have happened lower sales/buys but for the persons who are not familiar with current prices you should be fine with these ranges. All higher sales are very sketchy and should cause high suspicion. Trust me, these prices are much more legit than what most of the merchers will tell you
