Margaret Thatcher & Una & the Lion Medallion Issued by Pobjoy Mint. We photographed this medallion way back in October 2006. As it it now May 2007, you can tell we have been busy. It's now so long ago, that we cannot find the medallion, so that we can complete this page. To some people it sounds ridiculous that we can mislay stock, but we buy in so many different items, with a wide range of values, that it is not always practical to track everything at each stage.
