Hello, just wanted to break the ice on this unusual as it currently has no set price. I have analysed the prices of Miami nights in other price ranges and I have found that it is similar to the set price. I have also found 2 of them for sale on outpost, not bad proof considering there is only 4 in existence. As of this a fair midpoint should be around 1.4 buds.

Low Value Proof:

Selling for 20 keys: http://www.tf2outpost.com/trade/22811713

Selling for 21 keys: http://www.tf2outpost.com/trade/22910005

High value proof: As you can see there is only a 0.1 bud bud difference between the Madame Dixie and The shooters soli topi. Which makes sense to have it within a similar price range as the Miami nights effect is worth 1.6 buds.
