Hi, hhbkiddo, it is called Picture Merge Genius V2.8.1. found on the web.
I downloaded it for free.
Seems that it has a trial period you can use it on for personel use.
Not the greatest, maybe some better ones out there, I will still look and play around with this, However the one drawback I found now is that the pic must be perfectly aligned on the axis to match, So one can pick up Die rotating errors too.
You can do side by side as well as all the normal basic editing features.
The trial version adds words to the pic.
Here is a low resolution(Bad) picture of a 1894 ZAR pound I merged and offset it slighly so one can see the transparent top pic.I now align it on top and play with the slider to look at both coins.
