How are the Gem values worked out?
In the Steam Auction, every Steam item (card, booster pack, background and emoticon) has a gem value, which is awarded when the item is "recycled" (user clicks the Turn into Gems... button).
How is that gem value worked out? Is there some sort of biasness for rare items? Valve-made items?
I've noticed that all the sale emoticons/backgrounds are worth 100 gems each, along with items from Valve games^, free-to-play games and sales, while all other games only reach a maximum of 80.
^CS:GO somehow fits this rule, but Half-Life 2 doesn't.
