Idk. Im 27 now and I started collecting pins when I was 16. Ive noticed a big upswinging trend of younger adults getting into the hobby. I know when I was 16 the pin community seemed like it was comprised of a much higher age median.
As for pricing. Its mellowed a bit since last year at this time. Will it ever go to the old prices? Probably not until a whole generation of pinheads pass away. In other words. I feel prices are rather stable at the moment with a slight downswing in pricing.
