I have been getting rolls of presidential dollars at my local bank (usually to play poker with), but I always look at them closely to see if there is anything out of the ordinary. Here is what I found I my latest roll of John Quincy Adams $1 coins: When all the coins were placed in the same diretion, Obverse to Reverse the edge lettering is not always facing the same way. On some of the coins the edge lettering is actually updside down unless you would flip the coin over and read it that way. In other words it would seem that there is no consideration of how the edge lettering is oriented when the planchets are struck, unless the roll I viewed was an anomoly. Would this constitute a variety of a $1 coin?? In my roll there were a lot less of one edge letter direction than the other.
As Coleguy said there is no orientation to the edge lettering PCGS and NGC call it Pos A or Pos B on there lables but there is no premium. When the New Presidential dollars first came out the Washington Dollars where listed on ebay as upside down edge lettering and people paid insane prices. The Mint released a statement as to the minting process back then to quell that.
