petecldIt is defintely not uncommon for there to be legitimate size variations with "T" or "E" cards of this era. same for "N" cards I'm sure. I have one E card that is almost 3" tall.
You have to look at each card seperately if you are looking for trimming. You can't assume if it doesn't measure full it is automatically trimmed.
Some signs to look for: opposite edges that aren't parallel, drastic changes in edge wear from edge to edge, sudden angles at corners, "bat ears", edges that have any type of curve to them.
Post scans of cards you are questioning. This board will have no problem offering their opinions.
