Doubled edge?

Hello everyone I have been seeing this doubled edge effect on a lot of pennies lately, I know I have seen this before on here I just don't know what it's called, what it's caused by, and what it is. Anybody have some information?

On this coin, yes, it is obvious by the wider rim on one side. There are other causes that will give a rim that "doubled" appearance, collar clashes for one and an actual doubled die where the rim is doubled on the die.

 

Not a railroad rim. Those are struck partially out of the collar. Misaligned die.

 

Railroad rim.

 

Minor mis-aligned dies are
fairly common on most
denominations; they are more
like anomalies than errors.
