IMO it would be difficult to resell the amplifier with the damage shown in the photos. Possibly its present retail value for resale is around $500.00. Your photos don't show the area of the box that was damaged in transit, if there is any damage.
The box that is shown is intended for transport from a manufacturer to a distributor/retailer in bulk on a pallet, not for shipping through a ground carrier with multiple hub transfers, conveyor belts and the potential for mishandling.
