A number of factors
As a number have said - my opinion is past "public" sales (lacking all the private sales data which borders on impossible to accurately collect and track!) are 1 relevant piece of information to consider. More relevant when there are more sales in a recent shorter block of time and of cards of equivalent eye appeal (sometimes difficult to tell from digital pics). Supply/demand/availability? Many try to boil pricing down to a science and it is so far from it - much more art. At the end of the day - buy what you like and pay what you like as long as you have a seller willing to sell it to you!
