Here is how I was taught...
Take one example each of the a 1971 S uncirculated, 1972 S uncirculated, and 1973 S uncirculated. It has to be the "blue Ike" uncirculated coins, and not the "brown Ike" proofs. The 1971 has the Type I reverse, the 1972 has the Type 2 reverse, and the 1973 has the Type 3 reverse. No book or computer needed, easy to remember, and it gives you the excuse to take a good long look at coins that you probably already have. And if you don't have the blue Ikes already, it gives you the excuse to go out and get them.
