askea's link is very good. It mentions several theories for the use of cup-shaped coins. The old theory that "they stack better" has been repeated many times and that erroneous theory shows how little the scientific method leaps to mind among average readers, and how hard it is to kill off a bad idea. Anyone who has access to a dozen of these, say, from a hoard, can try to stack them and see it simply doesn't work.
Try bouncing a lot of light around the room but have none directly on the coin or use a ring light that lights evenly from all sides and wiggle the coin until you see the glares from the coin in places that strike you as pleasing. Coins are metal and metal has glare. The secret is playing around until it looks like you know what you are doing. Every time I get a cup, I start over. I will point out that you must have some glare on a metal object to keep it looking like a 3D metal object rather than a flat plaster cast. Copper plays nicer than gold or electrum. This is Alexius III with a bent edge.

Thanks for posting all of your coins and for posting those cool links (it ended-up being a very sweet thread) Cheers

Christ is enthroned on the obverse, and the emperor is wearing a chlamys; Isaac II is wearing a loros on his S.2003 trachy. To the right of the akakia, the inscription KOMNHNOC will be partially visible on most specimens.
