Its not
100 Rubbish Bronze pack
505 Silver 1 rare
509 AND 510 both more than 3k
610 x
615 x
620 X None of these 3
Just put 3k on second account if it says you dont have enough coins it isnt the old 910....If it opens it will either be the 910 or something worse like a silver pack or bronze time consuming i know but its just gonna be trial and error...
Is there a possibility that it could be 00910...? If so screwed cause the amount of possibilities
