It's incredibly easy to make a mistake with attribution. You can stare and stare at a given coin and come up with different conclusions every time you look.
If you Google 1908 pennies, and look at the LCA result for that, you'll see many, many misattributions for that year. Pennies passed as either F164 or F165, when they're actually 166. Although making a mistake with the 164, is pretty bad judgement, as that one is very obviously different.
