I've noticed through a lot of roll searching that, obviously, the '40s and '50s are the most common. However, I've found some earlier than that. I decided to take a look at the PCGS price guide. Of course, I know that most of those values will not be the realized prices on your coins. However, I noticed that the 1936 pennies are much higher in value on that guide than the others. Is this true in general or is that just from that guide?
