I don't think that it could be Taunton as only Elfric minted there. Taunton on Henry I coins is "TANTU" That "P" looks like a blundered "T" and so it might read "CANTA" "Pilde" at Canterbury is very confusing as there was no "Pilde" for Henry I mints... So perhaps Winedi, Willem, Wulfwine or Wulsi. I have a feeling that it might be Wulsi but it is an odd coin.
