I have a question regarding cues containing ivory. I have read the information on AZ Billiards but want to be clear. I have a cue that i bought on AZ 5 years ago used that has an ivory hoppe ring and ivory joint. The shaft ferrule is also ivory. I am thinking of listing it for sale or trade but since I am not familiar with the law I wanted to make sure that is permissible. The laws are really confusing so I need clarification before moving forward. Any guidance would be appreciated.
