It isn't nearly as simple as Jason says. His post is actually riddled with misinformation. I'll take a little time to offer corrections:
1. Blank backs appear in both M101-4 and M101-5 and are the most common back found in both sets.
2. MOST of the numbers are different between the two sets, so that a card of a given player can usually be assigned to one set or the other based on its number. However, in a few sections (#1 to about 10, again around 140-155, and 190-200), the numbers are the same in both sets, and there identification can be difficult.
3. there are some backs that appear only in M101-4, others only in M101-5, and others in both.
Jay is right, this topic has been discussed extensively in a number of earlier threads. A quick search of "M101 backs" will pull them up for you quickly.
Jason, the others who posted and recommended the previous threads WERE trying to be helpful. Instead of flaming them, maybe in future you yourself should take the kind of time you criticized them for not taking, and do a little basic research on your facts before posting such elementary errors.
