Queen Isabella: Would America Exist If Not For Pawn Shops?

I don't have as much time tonight, so I'm going to make this one short and sweet. A fun fact that most people probably weren't taught in their history lessons is that Queen Isabella of Spain pawned her crown to help finance Christopher Columbus' voyage that led to the discovery of the Americas. This is has been debated, and some people are saying that she didn't actually end up pawning the crown, but she was at least documented as saying,

"I will assume the undertaking for my crown of Castille, and am ready to pawn my jewels to defray the expenses of it, if the funds in the treasure shall be found inadequate."
