"40 million... 40 million US dollars!"
"How could this crown possibly auction for so much money!"
"It has actually reached 40 million US dollars now, this... this crown..."
...
When the audience heard that the bidding had reached 40 million US dollars, there was once again an uproar throughout the venue. No one had expected that this auction would fetch such a high price. An item fetching 40 million US dollars is rare even in specialized auction houses in Europe, let alone at a charity auction. Selling for 40 million US dollars is simply unbelievable!
