V), values from £2.88 to £28.60, each overprinted large format 'CANCELLED.' A fascinating group about which very little is known, the group unlisted by Booth, though he mentions the earlier decimal issues of this design are 'thought to be essays'. In our view it is far more likely these saw internal usage for accounting purposes and were not on sale to the public. In any case a fascinating and scarce group, ripe for further research. - P212010977\u003c\/p\u003e","brand":"Stanley Gibbons","offers":[{"title":"Default Title","offer_id":56193318420857,"sku":"P212010977","price":225.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0950\/9709\/4521\/files\/P212010977-1.jpg?v=1763039396","url":"https:\/\/shop.stanleygibbons.com\/products\/gb-c1975-revenue-national-insurance-multiple-contributions-p212010977","provider":"Stanley Gibbons","version":"1.0","type":"link"}
