Harry Potter Was So Rich, It's Knuts!

"In Chamber of Secrets, the Weasleys completely emptied their vault which consisted of one galleon and a pile of sickles, which could be equated from $50 to $75, and they had to buy everyone books, plus robes, a wand and cauldron for Ginny, etc. It didn't really hit me until now just how hard the 50 galleon fine for the Flying Ford Anglia hit the family.

"Also, it made it that more surprising to me that when they win the 700 galleon Daily Prophet Grand Prize, they spend the better part of $17,500 on a trip to Egypt (I suspect that a good chunk of it may have been spent getting out of debt, but they didn't tell any of the children). Finally, it meant Fred and George's 37 galleon bet with Bagman was over a thousand dollars on something of a longshot."
