I have read many threads like this and there are a lot of people that make a convincing argument that the price of pins will plummet. I am not so sure. What I do know is I can’t see myself stoping looking for pins, and I think you would be hard pressed to find anyone in this forum that would say they could take it or leave it. If current collectors are staying collectors and new people are coming to the hobby all the time, I think growth of the hobby is assured. (Growth = rise in price as demand v availability) However I do concede that one day it will go out, but that will be when we that grew up with pins die out.
Are good pins going to rise in price in your life time?......As sure as the price of stamps will rise.
Is a good pin an heirloom that can be passed on to your kids as part of their inheritance?........Can’t see it.
