September 28th in the year 869 AD
After hearing the vocalized bid of one hundred thousand gold coins submitted by King Donald the Second for the iron hand cannon, the crowd of commoners standing outside the stone building reacted immediately to the numeric value.
This specific amount of currency equated to the total material output of multiple populated regions combined over several decades of continuous labor.
The crowd of people outside the building began to shout and move their bodies rapidly, creating a loud noise that traveled through the air and penetrated the glass windows of the auction hall.
They reacted this way because they understood that such a massive transfer of wealth would alter the balance of power among the kings and provide the Iron Kingdom with an immense surplus of resources to fund future wars and construction projects.
