How to play Treasure Of The Dwarves

About Treasure of the Dwarves, from BoardGameGeek:

Deep in the mountains of the dwarven realm is where you'll find the best deals! In Treasure of the Dwarves, you place treasures up for sale, then evaluate secret bids from the other players. Consider their offers carefully because once you look at a new bid, you can't go back to a previous one. Some treasure is just worth points; others provide special abilities. Only the shrewdest deal-maker will come out on top! Everyone is involved on every turn of the game as you puzzle over how to collect coins, gems and magical treasures. Knowing what your treasure is worth is important - but so is knowing whose offer to look at first!
