They're surprisingly common and that's among the worst examples I've ever seen! Keep looking (on UK eBay) and you'll definitely find a much better one for less than £30. As mentioned above, the rarities (which are VERY rare) are the miss-spelt 'PENNEY', the dated 1844 and the all silver examples. There are also lots of micro-varieties, for which there's a book published, should you be interested in researching further. Do you know the name of the book cheers Not sure of the micro varieties book but Freeman's book covers a lot of the model pennies and has plates as well.
