The closest match to this seal is No. 65 Fig. 20 Egan, Lead Cloth Seals and Related Items in the British Museum:-
"Shield with ridged cross obliquely counter-shaded, DE.LONDI.NO. and wreath around." But the diameter is given as 24mm and this seal is 34 - 38mm in diameter and much of the edge appears to be missing. It could well be the back piece to No. 66 Fig. 20, See Gloria in Excelsis seal
