ArtI agree with your signature -- it's my hobby, not my investment. As a general rule, if I am not knowledgable enough about a stamp to make an intelligent judgment about it, it doesn't go into my collection. I am not making an investment; I am having fun. Learning about a stamp is part of the fun for me. Of course there are exceptions. If I simply do not have the technology available (ink analysis etc.) then I would consider a cert. I have some certified stamps but I purchased them based on my evaluation, not the certification.
When my stamp albums are permanently closed, I'm sure my kids will put my collection up for sale. Will they make money? Yes, because their cost is virtually zero. Will they get what I paid for my stamps? Highly unlikely. Maybe they will get 30% of what I actually paid. The lost 70% is the "price" of enjoying my hobby. If they want to spend money to certify a stamp, that's their decision.
If I planned to sell a "hi-value" stamp (unlikely for me!

) I might consider a cert to calm a nervous buyer.
