alt Hacker NewsA thousand years? What made you go with that number?
The protestant reformation was only about 500 years ago, and I'm pretty sure that Martin Luther wouldn't have bothered that much if the expected "donations" were really cheap. And even if you do go with "a coin", which was apparently the price of an annual indulgence for a regular peasant, that was about the same price as a whole pig, or on the order of $1k in today's money, so definitely not symbolic.
I know that hackers here need to always be right and go to great lengths to try to distort reality when they are wrong. You're not even fooling yourself by saying that every coin in history is worth a thousand dollars, much less fooling anybody else.
If you make it a habit to always lie in order to always be right, you start building castles of lies that hinder you in life. Just because of pride.
