Everybody has a different reason for why or what they collect.
Bottom line
You don't need a reason for anybody. Collect what you like and don't worry about what others think. Collect what makes you happy.

J18
Second cue from the left is a J18. It is from the very late 80's or very early 90's. I think I got it in 1991.
This one has the gold letters at the joint.
i have seen them with the plain diamonds as well as the notched diamonds.
