m101-4 and 5 question
 

Everybody's favorite auction house had this Ruth card on their last auction. I love the m's but am finding it hard to spot the inconsistencies of these cards reprinted when looking at a scan. Would like to know what to look for as the obvious signs (other then its in a Coachs corner auction obviously). thanks!
