OK. An Oxford Crown then (the V is roman numerals for 5 shillings). I have found a picture, so when you get yours on-line I will compare. The style will tell if it is a modern copy for souvenir purposes. If it looks like the 'real thing' further investigation will be needed. Do you have a scanner? They can be used to get fairly decent pics (all mine in the gallery were done that way). In the meantime, may I ask where you got it (I don't need real specifics, just was it a find, inherited, purchase?)
