OK! I'm getting serious now! It has puzzled me for years as to how people used the very small coins proliferating history. I mean the likes of Celtic units, Roman Quadrans and English hammered silver farthings. All of these were around 10 mm in diameter. When you think of being paid in that size coin you must wonder about how they kept the coins, in a purse or pouch etc without many losses. When you realise the value in material terms of an Edward III farthing it must have been very traumatic to lose one!! Any thoughts?
