I still have my Coin Monthlies from that time! Amazing how every other dealer advert was for "investment opportunities" involving massive numbers of common BU late 60s coins. What was heartbreaking was the prices of early milled where it was on offer - 1675 farthing GEF £12.50, anyone? In one of my old mags the 1960 crown was claimed as the nr 1 investment....common G11 silver such as 1758 shillings or 1746 lima halfcrowns were cheap as chips....I think a study of the web,auctions can now identify true rareities.
