PC jade wind orbs

I have 5 stacks of jade wind orbs, i heard they might be valubal - an old PC form says 15-20e each orb is that possibly right?

Thanks for the info

The person who i sold them to was very understanding and kindly reversed the deal for me. I will be holding onto them now until an eventual sale but if anyone can help with quantifying value, both if i sold them all together or 1 stack at a time i would appreciate it
