My thought too!Well, in a bit of a threadjack, my view is it's worth remembering there are no fixed prices for coins. Yes, due to popularity and availability Spink does influence what people demand or are prepared to pay, but in the end it's down to buyer and seller on the day. For some coins such as a 1727 shilling it's possible to establish, for a given condition, a narrow price range below which one would have to be very fortunate to find an example and above which it would be foolish. But with hammered coinage it's much more difficult to be precise. On a given day a buyer might be prepared to pay a lot more, or a lot less, for a particular coin, whatever the 'book' value. The Americans (primarily) have tried to pin things down somewhat by use of third party grading and 'Red Books' etc, but that only works with modern machine made coinage .. and even then there will always be disagreement! The 'best' solution is a good knowledge of your chosen coinage and the market. However that's not easy. I collect one denomination from a narrow range of years but I have over 1500 records of Charles I shillings and their price alone. And that doesn't include the examples I decided were too worn or horrible to bother about. And yet prices at auction can often surprise me, either seeming far too much or conversely cheap for a given coin. To me the usefulness of Spink is to find out more about coins that I don't know well. The when I've pinned down type and variety I can use auction records and dealer listings to get a better idea about prices. Even then, what one coin sells for today is no guarantee what it will sell for tomorrow. There are fashions in coin collecting as with anything else and what is popular today, tomorrow .. who knows! .
