I will take new full photos and repost. I’d like to see how they turn out, too. The holders are Lighthouse Quadrum. They also sell display trays, and I will try to get a photo of how a tray of SLQs looks.
First, the tray with the holders. There are a mix of two kinds of holders - about half of each type - a matte plastic Whitman 2x2 and the Quadrum with the black insert. The tray is a blue velvet finish with cutouts to fit each 2x2.
To (probably) wrap up the thread, here's a new animation of the coin, now that it's out of the slab. It looks more like a full head here than in the previous pictures. Even if it may not be full head, the forward leg is fully rounded, the shield rivets are sharp, the sash is well contoured, and the luster is terrific. It's too bad there isn't an appeals process for the original seller to get their money back from the UNC Details grade. That grade just doesn't give any useful information at all. I'm glad I was able to buy the coin in spite of the holder.
