You need to get a couple of books, William. 1) Collectors Coins GB, about £7 by our glorious leader, Chris Perkins 2) Grading British Coins, £13 by one of our favourite forum members, Derek Allen both available here, probably the best £20 you could spend. Same price as fish and chips for 4. You'll be glad you did! Has it got an inverted 1 in Victoria - my bet is that it has !
