Thanks everyone:) seems like a really great forum, i appreciate the welcomes and advice!. Looking forward to receiving this grading book as i have just remembered i also have 5kg of old pennys , half pennys and farthings ect. Maybe i can get rid if some duplicates and lower grades and get some coins i don't already have. Really like the idea of some crowns with silver content, i have plenty of crowns cupro-nickle and lots of 50% silver half crowns but no silver crowns yet. just ordered another 400 grams of varied pre 1947 silver, Im buying a lot, its better than wasting it down the pub lol.
