What is fair for a Tink Valentine's '06 pin?

[PaperDolly]

I have a valentine 2006 pin and someone wants it, she has lots of rare and I can get pretty much anything, the problem is I dont know what is rare and what isnt, what is valuable and what isnt. Does anyone know what a Tink pin is worth on the vmk market these days?

i can't put an exact amount on it... mind telling what items she has?
