The price on Harry’s head
As Voldemort came to power, Snatchers were rewarded 5 galleons ($125) when they handed over a captured mudblood to the Ministry of Magic. However, the user writes, “The Ministry was willing to pay $2.5 million to capture Harry.”
To put this even more into perspective, the reward for catching Sirius Black was only $250,000.
Edit: The values were different in the books than they were in the movies, which is why the bounty amount on the poster says 10,000 Galleons instead of 100,000.
