Nagal staff

The Grand Nagus's staff was a sceptre carried by the Grand Nagus of the Ferengi Alliance as a symbol of his authority and power. The figurehead was that of a Ferengi man.

It was traditional to kiss the staff when in the presence of the Nagus. 

Grand Nagus Zek had to use the staff as a cane due to his advanced years. When Zek retired in 2375 and named Rom as his successor, Zek also passed the staff to Rom. 

When Jean-Luc Picard saw Rom with the Grand Nagus' staff, Picard thought it a wonderful prop to impart stature and majesty.
