Hi guys, i'm just going to post a video on photobucket to prove this, i'm not sure whether this is significant or not, however i've found an 1884 half crown that i believe has its reverse upside down. Open to debate as i honestly haven't got a clue, were they made this way? http://s1274.photobucket.com/user/CVarnz/media/Video3_zps94e1e137.mp4.html
