I don't believe this is an error, and here's why.
Date: it looks pretty normal for a circulated coin. Perhaps you could point out where you're seeing doubling.
If there is doubling, it can take a bit to learn the difference between a doubled die (usually rare and worth something) and Machine Doubling
(very common and rarely worth a premium). Doubled dies actually widen the coin's details and produce telltale notched corners and serifs, while Machine Doubling
just flattens part of the device.
LIBERTY: It looks like the E and R are damaged. You can see where the upper loop of the R used to be, but a hit shove the metal to where it is.
Rim: It's just worn down into the field. A partial collar strike is what happens when the collar doesn't cover the full thickness of the coin, so part of the edge can expand beyond the normal diameter. Here's a good example: http://goccf.com/t/394723
Feel free to measure your coin's diameter, but I suspect it's no larger than it should be.
Sorry it's not an error, but this is how we learn.
