.... That is the beauty of TRUE collecting it does not matter is ANYONE else wants it, you do. I have many chips and banknotes NO ONE ELSE wants but if I did not have them in my collection there would be a 'hole' and "I" wanted them.

I sell/trade a few dups from my collection but I am not in it for an investment, I am in it for pleasure and don't really have any plans to ever sell my collection for a profit or otherwise. So, because no one else wants something does not make it valuable to "Someone".
