A question not on the latest chapter but ch4:

McGonagall shook her head. "Your father was the last heir of an old family, Mr. Potter. It's also possible..." McGonagall hesitated. "Some of this money may be from bounties that had been placed on You-Know-Who, payable to his ki-" McGonagall swallowed the word. "To whoever might defeat him. Or those bounties might not have been collected yet. I'm not sure."

Did we ever find out whether the bounties were collected? I was wondering whether 40k Galleons was a reasonable sum for last heir of ancient family + entire wizarding world's bounties on Voldemort, but I can't remember the question ever being answered in the first place.
