Chest Gambling

Yesterday while playing I thought of an interesting idea that would bring some content to the game: Chest Gambling. Basically how this would work, is that you can either open the chest to a prize that is a more expensive or worthless item than the the actual chest, making the chest itself not sell able anymore, or not opening the chest at all and being able to sell it at base price. This would give another fun way to make some money, but at a risk.
