I will offer my thoughts as a coin roll hunter of
Jefferson nickels.
My immediate reaction is a question: where do the lights, scope, and fingers go? Inspecting large numbers of coins at once generally requires moving the light source and scope around, and also rotating the coin relative to the light. Is your plan to move the equipment or move your trays?
How would you move the coins around a fitted tray without putting fingerprints on the faces? Normally, I try to handle nice coins by the edge. Assuming the tray is used for screening, how easy is it to pluck a coin out and set it aside for thorough inspection?
How easy is it to drop coins into the trays, versus just a cardboard sheet? Your pictures show the coins as all oriented the same way, but that takes handling. How easy is it to drop them in quickly and then rotate them the same way? For example, I examine all modern nickel reverses at a 150 degree rotation, with the light coming straight across, about an inch off the table.
I do like that the coins could (theoretically) be flipped all at once.
Are the coins dropped directly from a roll, or do you envision a pre-sort process?
How do you remove the coins when done?
This seems like a situation where a usage video would help to demonstrate your concept.
