I have interpreted the runes on the R8 Sceatta featured in this article as HHL. The runes HH appear to be ligate or bind. The rune graphs are discussed.
Many different combination of runes were used on the obverse flans of the R series, EPA, GEPA, EA, EP, ER, RHY and SPI were the most common, ES is quite unusual. I have only observed EAP on one coin, presumably an error by a die cutter. The later Wigraed (R10) and Tilberht (R11) coins had their names in runes.
I have only seen the combination of runes HHL on two coins I own and one more registered on the Early Medieval Corpus database at the Fitzwilliam. The symbols outside of the standard on the reverse of the “Angry Face” coins are also discussed.
