Rhett YeakleyFrank, the serif is definately tougher than the other, if I said anything other than that in the past I was probably just writing too fast or not paying enough attention to what I was writing.
As someone that is interested in back variations, I will share another one I have found, but this one is even less exciting than the serif/non-serif E121 back. This variation involves the E220 National Caramel set, and the differences are minor but in my opinion legitimate enough to be considered a new back variation.
The main difference being the size of the print of the first line, and probably most-telling is the spacing between the words in the line "--Made only by--" on back. Haven't done too much research to see if one is tougher than the other but I have several of each indicating that one isn't necessarily tougher than the other (but I could be wrong). Just thought someone else might care about the small printing variances that are around, and uncatalogued.
