Edward I penny and some artefacts

Edward I penny, mint Bury St Edmunds obverse

At our club dig last Sunday I was fortunate to find a hammered coin, my second this year. It is an Edward I penny, minted at Bury St Edmunds.
obverse probably reads: EDWAR ANGL DNS HYB meaning Edward King of England Lord of Ireland

reverse reads: VILL SCI EDMVNDI meaning Town of Bury St Edmunds
Edward I reigned 1239 – 1307 and was also known as Edward Longshanks due to his exceptional height.
