Buyer's Premium
Buyer's premium is the fee added by an auction house to the hammer price and paid by the buyer.
What buyer's premium means
When a result includes buyer's premium, the public sale price may be higher than the hammer price. Wassily labels buyer's premium separately when available so users can compare records more carefully.
