If involved iƱ a store, yes. People veiwing the quality of my collection would speak volumes as to my knowledge of the coins I sold.
As a member of a club, yes. It is my opinion that people as a whole like to be affiliated with high standards of greatness.
If I had a substantial collection I would look for any place to show it off. Compared to the cost of thr coins, the cost of having them published would be negligible.
As a novice collector no. Not enough high quality coins.
