From Wikipedia: The Noble was the first English gold coin produced in quantity, having been preceded by the Gold penny and the Florin earlier in the reigns of King Henry III and King Edward III, which saw little circulation.
The coins on this page are quarter nobles. Full nobles and half nobles use other patterns. Quarter nobles weigh between 1.4 and 1.9 grams.
The face value of a noble was six shillings and eight pence (written 6/8), which was equivalent to eighty pence or one-third of a pound sterling. The weight was changed from issue to issue to maintain this value until 1464 when the value was increased. Throughout the history of this denomination there are many varieties of inscriptions, mint marks, and to some extent, design.
Very roughly, catalog values run like this:
worn: $500 US dollars approximate catalog value
average circulated: $700
well preserved: $1500
Our secondary figure gives and idea of how value varies with condition. The (A) coin is damaged itself, or was struck with damaged dies. It sold for $370 during a 2008 auction. The (B) coin has some wear but pleasing eye appeal. It sold for $500 during a 2008 auction. The (C) coin is almost uncirculated, showing little wear and no sign of problems of any kind. It sold for $1000 during a 2006 auction, and would probably sell for much more today.
