Ascendancy 3 problems

I've been having some trouble regarding the the 3rd ascendancy. I used it at the trials, but the modifieres on the preivous run applied there aswell, so i thought it bugged and got out.

But when i got out the green ultimatum trail coin or whatever its called, dissapeared.
I've been told u only have one try but its quite a common drop when u get higher level.
I havent seen it once since, which i thought was odd, so im asking you guys if its supposed to dissapear since is a green quest item. I'm pretty new to path of exile so i dont know the terms and such, so sorry for not being precise for terms and such.
