I would personally rate the above years poor to fair. A lot are missing spine covers, some are missing or have loose front and back covers.
The collection then jumps into the 50s and goes uninterrupted for the most part through 1995 and there are a few sporadic 2017, 2018 issues. These I would rate good to excellent.
Here are pictures of the earlier years from above:
Your asking price and location would be helpful.
Oh shoot - located in Texas. I'm not sure what a good asking price is, which is why I am asking if there is any interest. $200?
