I know a database for every player exists, but is there a list of prices for each player on HUT?

Well that's the point of an Auction that there is no set price. Most people sell cards at a premium to see if anyone if crazy enough to buy their cards. What you can do is set the BUY NOW setting at a low price and see what you get. That's all you can do. It's up to you to sell your cards at a set price not EA's. Ive made thousands working the market. Don't listen to the Average low's and high's either, they are never accurate. The market goes up and down depends if there is a 2x puck happy hour event. The market usually increases after happy hour, because people have money to blow at that time.
