I started by collecting coins from change as a child and ended up with a sizeable collection with many Victorian silver issues but soon discovered the joys of English hammered coinage. I began with the less-expensive types of Henry III, Edward I, Elizabeth I, etc. before moving progressively back and now my main focus is mid to late Saxon material, Viking issues, Norman pennies and the occasional early Plantagenet coin. My focus at the moment is trying to build up a body of high grade mid-Saxon material, but it's not cheap, so focusing on the pennies of Aethelred II, Cnut and Edward the Confessor are allowing me to do plenty of research. Hopefully I'll get around to publishing some papers next year.
