What is the highest amount of money you have been offered?

I received an email a couple of days ago offering me $12 billion that I had won in a Royal Bank of Canada lottery sponsored by Coca-Cola. The scammer even asked for the fee of $100 in the opening script, rendering the necessary level of gullibility needed to reply to the email higher. To put this into perspective, Coca-Cola is apparently giving away approximately 500 times the net worth of its CEO, and the Royal Bank of Canada is apparently going to give me enough money to make me richer than all but one person in Canada. I haven't bothered to reply to this email yet but I'm wondering if anyone has been offered a higher sum of money and what your thoughts are on why a scammer would use a script like this (I know they often buy scripts, so maybe this one just went with a cheap option?)
