I'm not a professional grader, so my opinion is just from a general collector's view, but to my untrained eye, the comics appear to fall around the following conditions:
X-men -1: Near Mint Minus / Very Fine Plus
Uncanny X-men -1: Very Fine
I ship with care! Your comics will be bagged and boarded using premium 2 mil crystal-clear OPP bags (similar to mylar), then bundled face-to-face in a padded envelope, then that bundle will be placed in a Gemini II comic mailer for the journey from my house to yours via USPS Economy Media Mail. I've had tremendous success with this layered packing method and think that you will be pleased with the results.
Thank you!
