Mark, I always value your insights and you have far more experience than I. Two observations though ... It is recognised that separating investment strategies from collection or hobby strategies is an intelligent approachSupply and demand will always win out, the fact that the supply of old coins, stamps and fountain pens has of course dried up (except as Chinese replicas) does not mean that values will increase over time, demand is far more difficult to predict!These two points are of course obvious, but I make no apologies for restating them! I want coin prices to fall as a collector/buyer, and increase as an investor/seller - obviously! My bubble point relates to high end coins going through auction houses such as Heritage ... there is a built-in spiralling price effect due to the hype and commission, with some coins the whole house of cards will just crash down, which might have a knock-on effect. I don't operate at that level, so it is, as I said, just a feeling, watching from the sidelines.
