Which would you choose and would you do so because you thought it was worth the most? [See details]?

Imagine a well-dressed man wearing a bowler tells you that you have one choice of three options, but whatever option you pick, you have to keep because you can’t change your mind. The options being, you can have the amount of gold nuggets that will fit into a standard mailbox, the residential type on a post. The amount of diamonds from .25 caret up to 3 caret, that would fill a 10 gallon Stetson cowboy hat from crown to brim. Money bricked in $1,000 lots enough to fill a standard size cargo van, not the extended one, from ceiling to floor, wall to wall, from the back of the driver and passenger seat to the back doors. Which option would you chose, and would it because you believed it was worth the most? If you only had 90 seconds in which to choose what would be the method you would use to make the decision, providing you didn’t panic and blow it all together?
