The elders among you will probably remember something similar in the 60s for 1950/51 pennies, except back then communication wasn't as quick and things didn't explode onto the scene like they do with the internet now. It is a fact that there is (through whatever reason) huge demand for the Kew 50p at the moment, for example. So prices are high and I think they'll actually stay high for quite a while. They won't rise especially, but these hype situations have a long residual effect. I think a lot of people see these things as an investment, as if it were easy to invest in coins with little or no basic knowledge. They buy them for their children, grandchildren etc and it's mostly people on low incomes from what I can see. There is a massive interest in decimal coins at the moment, and I suppose that can't be a bad thing. 1 in 100 will go further than just the stuff the media feeds them!
