The cut lines on the standard topps set appear to be about 1/32 of an inch so it would be safe to assume a card showing a white strip edge greater than that is a MB card as long as it was located on the inner rows of the sheet, correct? However, if a standard Topps card was located on one of the outside rows of a sheet and was miscut it is still possible for it to possess a greater strip of white. After looking at some of my '68's it also appears the cut lines weren't always as white as the one shown in the pic you provided...if I'm seeing it correctly it appears some were brown and others were a very faint white, are others finding this?
