Need tips when viewing shiny coins

collectorof2much

Since I'm new at trying to distinguish if a coin has any errors I am looking for some help. It seems that every shiny coin viewed up close shows halos (for lack of knowing the proper term) around the numbers and letters which can look like doubling (maybe doubling is not the proper term either) at times. I'm assuming that knowing the difference just comes with experience but I would appreciate any tips on the subject. I've included 3 photos of a 1971 D lincoln cent which is a good example of what I'm talking about, it looks like doubling with the 9,7,1 & maybe even a D over a D?
