All of the Harrah's Reno Babe Ruth strikes had the edge lettering, 2 have the short edge lettering you are showing and 4 have longer edge lettering. The edge lettering is showing the item on the strike has a copy right.
The 714 Homers and the Centenial have both short and long edge lettering while the Batting Average .342 and the Hall Of Fame have only the longer edge lettering.
There is also one that has the edge lettering doubled, it is an error and is found on the Hall Of Fame strike
