Usualy case contatins itemes


 * 4 blue  (standard 50% chance)
 * 3 purple (uncommon 25% chance)
 * 2 pink  (rare 15% chance)
 * 2 red   (elite 8% chance)
 * 1 yellow (legendary 2% chance)

Event items are usually distributed in the same way. But they can only be purchased during the event and never again. This makes the value higher.

So we will assume that the event blue item costs the same as the average price of red non-event item. Ok since purple item drops out twice less often as blue.

142 * 2 = 284

Means a purple item is worth 2 times more costs.

284 * 2 = 568

Pink item is worth 1.6 times more costs.

568 * 1.6 = 909

Red items is worth 1.9 times more costs.

909 * 1.9 = 1727

Yellow items is worth 4 times more costs.

 1727 * 6 = 6908
