The Dragon's True Wealth

Rein's golden eyes moved to the host.

"Yes." 

Following that, a bag of moonstones was thrown down to the host. The host immediately caught the bulging bag. Even without counting, he knew by its weight just how many moonstones it contained. 

One hundred fifty moonstones!

One moonstone was the price of the lowest seat and was the minimum fee to be able to participate in the auction. Five moonstones for the middling ones and fifty moonstones for VIP seats. For VVIPs, it was priced one hundred moonstones per cabin. They were the highest priced seats.

The extra fifty moonstones were clearly the extra tip for the staff of the Alliance managing the auction. The host himself has a share.

Despite the initial fear, the host's eyes lit up. Fifty moonstones as tip? So generous!
