Toning makes it tough for me to determine grade and what if any wear there is on the coin. More experienced eyes, where you see this one grading at? https://www.ebay.com/itm/145190029413?
One can only tell so much from photos, but it looks like enviro damage to me, too, and a grade from a TPG would come as a surprise to me.
"Better than the images", the seller says. Well, then, if you want to get reasonable money for the coin, POST BETTER IMAGES on your listing. As it stands, it looks like it's not worth the opening bid. I can barely even make out the CC.
