Hello, I'm kind of new to this trading business. Little help?

[Stalgrim]

I'm looking to get a specific item that I've wanted for a few years, an all class beanie-style unusual with scorching or burning flames. Specifically : https://backpack.tf/item/6918779379

 

Is there anything I should know before taking the plunge? Is there any chance the item is duped or what have you? Is there a more specific price the item is worth that I might be overpaying?
