When and how do you decide to have photos PSA-certified?

I do want to apologize if I am repeating myself or if the question has already been answered. I make notes on the post that everyone has posted, thanks, and post or ask questions based on those notes. Therefore sometimes the question has already been answered or maybe I repeat myself, because I am not fully understanding the information provided. Thanks for being patient, I just want to understand the information provided. In the past before I found net54, it was hard to get information or even have a conversation. A lot of people for some reason or another just did not give out information. Thanks John.
