Price last set 5 months ago, which with how Noh Mercies are rising, is an eternity ago. Let's begin:

2 Steaming Nohs were all that got unboxed before they were accidentally discontinued when Valve switched them from a hat to a misc item in Mid 2011. One of those got duped (Level 46), so there's two level 46s with the same original ID. The only other one (Level 8) is clean.

Of the three that exist (2 dupes, 1 clean), both dupes are on Outpost.

First trade: http://www.tf2outpost.com/trade/11736016

- Caudrun Bubbles Executioner = 11.6-14.5

- (Cleanest on the market) Purple Energy El Jefe (priced 7.8 buds here which seems kind of conservative) + 1.5 buds + sweets = 9.3+sweets

Second trade: http://www.tf2outpost.com/trade/11743824

- Ghosts Bubble pipe (5.5-6.1) + 3 buds pure = ~8.8 buds http://puu.sh/3CjSM.png

- Stormy Storm Tavish Crown (1.4) + 8 buds pure = ~9.4 buds http://puu.sh/3CjSM.png

- (Cleanest on the market) Purple Energy El Jefe (priced 7.8 buds here which seems kind of conservative) + 1.5 buds + sweets = 9.3+sweets.

--- This person also said he's willing to add to his offer.

Again, these are for the dupes. The only clean one has not been on the market for a long time, but would surely garner slightly better offers than these dupes.

The current price is extremely outdated; it would be impossible to buy one for DOUBLE if not TRIPLE the current price of 3.5 buds.
