You hardly will get more than 0.5(what most sellers ask), mainly because you can get at most 0.4/month on primedice signature with a Senior.
I've seen Senions accounts sold by around 0.3-0.35, but without avatar.
my price is appropriate. The account is worth every bit of my asking price although I am willing to discuss offers.
I can see by your prime dice signature that you are trying to pad your post count
