A try on rare Values --

I tryed to come up with some values --

Petal Patch - 3.0 - Most of the time in a Casino or trade you are most likely always going to see someone scream out "3 Hcs for my petal" and I have been seeing this a lot,
Mocha - 0.5 - These are mostly used to add in that extra 0.5 to your trades so it stays the same, same with dicemaster.
Bronze Nelly - 3.2 - Well I see some peopel trading this nelly for 3.5 and the silver lower. Then again you see alot of people asking for just 3 HC's pure.
Silver Nelly - 2.8 - I see alot of these going for about 2.5 - 3.0. Most around 3.0 so I would say about in the middle of that.
Throne - 20.5 - Alot of people take this in casinos or trades seeing as they always want profit. I see alot going for 20 - 21.

Like i said in other Rare values post.. those are also good Values :)

Keep it up, and Good luck ;)
