I have a 1746 Farthing not the best condition, but have found that Obverse is upside down to the Reverse. I hope you understand when looking at the Reverse with the date at the bottom and you turn it over like turning a page in a book the head on the Obverse is upside down. My question is this normal or have I found something unusual. I only ask as I do not have anything else of that age to compare it with. Any help appreciated please.
