Why is it that in Harry Potter and the Chamber of Secrets, the Weasley's are so poor that they only have one galleon and less than 17 sickles which would be a maximum of $19.55 in U.S. dollars or 9.71 UK pounds. But in Harry Potter and the Prizoner of Azkaban they win 700 galleons ($7,049) they use most of it on a trip. I think that there is no way that the Weasley's are poor enough to have less than $20 in their vault.

Possible explanation: The Weasley are sued 10 galleons for the Flying Car so the might have had more like $120 dollars before —The preceding unsigned comment was added by Kartoffelwunderbar (talkcontribs) 21:07, October 20, 2011.

The Weasleys may have lived hand to mouth, quickly spending each paycheck Arthur received on things necessary to support such a large family, and thus never getting an opportunity to create a substantial savings. When they won 700 galleons, their thinking could have been that they would never be able to save up 700 galleons on their own, and thus it made sense to take a trip while the money needed for it was available.

Thankyou Starstuff you saying that. I do think that it was still a really small amount to have in there.
