Can someone help me determine the value of my unusual?

I got an unusual el jefe with haunted phantasm jr. effect. (its 1 of 1) Ive tried to compare it with other scout unusual with same effect but the values that i've got trying to do that have been from 30 keys to 120 keys. Pls help!

 

So, I did a little research on that.
My suggestion would be to start off at around 80-90 Keys. Your Unusual has a nice Halloween Effect and it' also 1 of 1 wich should add a little to it's value, still I doubt that it would go for more than Green or Purple Energy El Jefes.
But always set your Buyout price high in the beginning to get as much as possible out of your hat. If you notice that you barely get any offers or if they are all way below your price you can still think about lowering it a bit.

That's just a suggestion not a 100% qualified guideline on how to sell your unusual.

 

Would also say arround 80-90,

Price doesn't really matter basically,

You can sell the hat for the amount you want to sell it for
Your hat is 1of1 and unpriced, which means that the price doesn't even matter. let's say you'd want 120 keys for it and some nice person is gonna buy it for that amount, your hat will be priced at 120.
~80-90keys is just an realistic value.

Hope we could help you out a bit, good luck selling.

 

I already sold it before i got to read this for 40 keys
maybe next time ill check the price from here before being dumb and selling it....
