From a TF2 raffler (don't want to put a direct link in-case it is considered advertising):

"Just trying to give you folks a heads up. The following items have been recently duplicated so PLEASE inspect your trades thoroughly. Valve is likely aware of the issue and will probably take action.

Max's head 7 LVL (Original ID: 251524473), Unusual Troublemaker's Tossle Cap Burning (Original ID: 297958481), Unusual Troublemaker's Tossle Cap Purple Energy (Original ID: 418195150), Unusual Chieftain's Challenge (Original ID: 449365543), Unusual Hermes Flaming Lantern (Original ID: 563825193), Unusual Sergeant's Drill Hat Blizzardy Storm (Original ID: 540952507), Unusual Carouser's Capotain Cloudy Moon (Original ID: 549692230), Unusual Hound Dog Scorching flames (Original ID: 278650093), Unusual Tyrant's Helm Scorching flames (Original ID: 228664397),

I doubt Valve will let that happen though, TF2 trading is a gold mine for them.

Looks like in game trading is currently shut down. It has been speculated that the way that items were duplicated is to trade via Steam Trade and in-game at the same time.
