Hello @TheTrachyEnjoyer
It's nice to see you again. I was rather unhappy, when you were banned from CT. No one seemed to know why. I figured, that it was probably something silly, and that's what it turned out to be, it sounds like.
Are you aware of the Abafil deep trays? They come with 24 compartments, 15 compartments, 6 compartments, and 1 compartment. They are items 132, 133, 134, and 150 on the following web page, and they are lined with red velvet (not felt).

I have a 24 compartment deep tray, a 15 compartment deep tray, and a 6 compartment deep tray. I measured the depth of the 24 compartment deep tray, and it was approximately 14 millimeters deep. That was the height of the vertical dividers. The horizontal dividers are slightly taller.
I'm using the 24 compartment deep tray, to store my "2nd string" thick coins and "2nd string" trachy coins.
I'm storing all of my "1st string" coins, in 1-compartment regular depth (not deep) Abafil trays, with each tray in an Abafil Diplomat 2 case, with only 1 tray per case. But, I have a lot of regular depth 24 compartment trays, in case I ever decide that I prefer the 24 compartment trays.
I use 1 tray for my ancient Greek coins, ancient Africa coins, ancient Middle East coins, and other ancient coins. I use 1 tray for my ancient Roman coins. I use 1 tray for my Byzantine coins. I use 1 tray for my ancient and medieval Chinese and Vietnamese coins. And, I use 1 tray for my Celtic, medieval, English, Spanish colonial, and US coins. Except for my Lincoln cent collection, which is in coin albums. So, at the moment, all of my "1st string" coins, except for my Lincoln cents, fit into 5 Abafil 1 compartment trays.
Here are photos of my 24 compartment deep tray, with my "2nd string" Isaac II bronze trachy coin in it. The Isaac II bronze trachy has a maximum diameter of 27 millimeters (and a weight of 2.89 grams).
And, here is a photo, of my "1st string" Byzantine coins, in a 1 compartment Abafil tray.
And, here is a photo, of my Diplomat 2 cases, and my Diplomat 7 cases. I keep all of my extra Abafil trays, in the Diplomat 7 cases.
And, here are photos of my "black cabinet", which is a Lighthouse case, with a single non-removable tray, of black felt and 12 large compartments. I probably have more than 1 fake, especially among my "2nd string" coins. But, I'm 99% sure that the Justinian I follis is a fake, and that's the only coin, that I'm so sure is a fake. The fake Justinian I follis has a maximum diameter of 45 mm (and a weight of 17.67 grams), so you can see how large the compartments are.
