Grand Nagus's staff

The Grand Nagus's staff, also called the Sceptre of the Grand Nagus, is an item that is held by the Ferengi Grand Nagus. It is traditional for an individual to kiss the head of the staff upon receiving advice from the Nagus. 

The Grand Proxy carries the staff as a symbol of the authority granted to him by the Grand Nagus. 

In 2371, Zek gave the staff to Benjamin Sisko to prove to Quark that he wanted him to help the USS Defiant (2370) to locate the Founders. 

While living in the Vic's Las Vegas Lounge holoprogram, Nog commented that a cane given to him by Vic Fontaine (a replica of a cane used by Errol Flynn) was reminiscent of the Grand Nagus's staff. 

As he passed the reigns of power to Rom, Zek also gave him the staff, a symbol of the power it represents.
