Edge and rim errors occur when collars are either out of position or are deteriorated. A wire rim occurs when excessive pressure squeezes out metal between the collar and the edge of the die producing an extremely high thin rim. A partial collar occurs when an out-of-position collar leaves a line around the coin which is visible when looking at its edge. A partial collar is sometimes called a railroad rim when a reeded edge coin is involved as the line resembles a rail and the reeds resemble railroad. The coin has a thin rim and apears to have a crack around the rim. There is also a line around the edge. Which gives the appearance of railroad tracks. The coin is in good condition. Any opinions?

You should be able to see reeding on the rim of a partial collar coin. Example here: https://coinauctionshelp.com/collar-die-clash-mint-error/ Also, what you called wire rim is correctly known as a finned rim: http://www.error-ref.com/finning/ I’m happy to see you searching out and using definitions for errors. Keep reading and learning! Www.error-ref.com is my favorite and best resource for learning about errors. Your photo quality could use some work; most photo issues deal with lighting and camera positioning issues. And please post them as full images after uploading (the button option will appear after you upload a photo). Also, we like to be very precise in numismatics. “Good condition” is actually not a great thing. See here: https://en.m.wikipedia.org/wiki/Sheldon_coin_grading_scale Hope I wasn’t too critical; I’m glad to see you researching and investigating.
I am at finned rim, this is also associated with off center and miss aligned dies. One thing though a collar clash with a reeded collar will always leave an evident reeded impression.
While I like the rim errors description, I don't think the 2002 Tennessee quarter is showing either partial collar or finned rim, imho. Here is one of my partial collar quarter. And my finned rim nickel before slab (NGC calls it Excess Pressure Strike)
Superb examples. I've yet to find either in the wild. Thanks for sharing. I was of the exact same opinion, but could barely see the coin with my smartphone.
