This coin is one that has puzzled me for a long time. Deep scratches indicate the same colored metal throughout, which makes me think this is not similar to the gold plated 1883 "No Cents"
Liberty nickel con. So I need to ask the experts to chime in with their "2 cents".
24mm width, 4.9 grams weight (as opposed to the silver shilling's 5.66 gram). Weight variance could be attributed to heavy wear to a 'G' state.
I can find no Krause or NGC references to a gold shilling of this date, but I did find that Christie's shows an 1816 milled edge coin touted as a 'pattern' shilling with the same abbreviated Obverse Geor. lettering and reverse phrase "Honi soit qui mal y pense", a.k.a. "shamed be whoever thinks ill of it". However, that coin weighs in at 7.97 grams.
Apparently the "Honi soit qui mal y pense" phrase origin was a trivial mishap at a court function. King Edward III was dancing with Joan of Kent, his first cousin and daughter-in-law, at a ball held in Calais to celebrate the fall of the city after the Battle of Crecy. Her garter slipped down to her ankle, causing those around her to laugh at her humiliation. Edward placed the garter around his own leg, saying this very phrase and founded the 'Order of the Garter' around the time of his claim to the French throne.
So, all that aside, could this possibly be quite a find or a very nice trinket/exonumia to snicker about?

Please be nice about my pathetic attempts at photos. I realize all hopes are lost for my ever receiving a photographic excellence award. Sigh.
