Quick sale: If you're not patient or don't get good exposure... I'm guessing $14 to $40.
Most likely sale: I'm going to guess a sale of $250 to $500 of you're willing to be patient and if i you get enough exposure. (see below historical sales)
Lucky sale: If you know what you're doing or extremely lucky... I can see it getting $1,500 or even $2,000 if the perfect end-user came around
