I am wondering if this is considered doubling of the pillars on a 1994 penny? Learning what to look for and what is and what isn't. Thanks.
1994 was generally a well struck coin from both Philly & Denver. So, you're likely seeing better definition of what the pillars should look like on a well struck coin. Doubling of the pillars, when it happens, are usually well separated from the host pillar. In other words they are more into the bay area than close to the pillar.
Doubled pillars usually happen in between two of the pillars on the on the die face and not the details.
And concerning doubling issues.. The correct numismatic terminology is Doubled Die.. You would say Doubled ear, Doubled columns etc. Not for a striking error though. That would be double struck because it was struck twice. In Doubled Die varieties the coin was struck once with a Doubled image that was created on the Die.
