Step into our time machine and travel back to early 19th century Europe. Napoleon has successfully invaded Prussia, an empire that once sprawled across much of Europe. The ousted Prussian government is now trying to fund the War of Liberation, which takes place 1813-1814. An appeal is issued: donate your gold and jewelry to the treasury, which will allow the government to raise money for the fight. In return for your gift, you will receive jewelry made of iron.
