I don't understand why this would go beneath the non genuine version, but I didn't down vote as there could well be a reason

It got sold for 3 keys on your links

Like it is with most items that have a genuine and unique version, the unique items are not as available so people put a high price on them. Craft numbers and rarity. Then when the genuines becomes tradable they flood the market and demand is satiated. I don't know about 5.22 ref, but they're not going for 10 ref.

I also dont get why anyone would value this at less then the non-gen... maybe wait until all the noobs are done quickselling theirs to change the price?

7.77 Ref is better -- 3 keys is ez
