They exist. My dad bought me a small
glass lid one (covering maybe 12 or 15 coins.) when I was a teenager. However, it was from the local, defunct,
coin shop. I don't think it has a maker's mark.
The same dealer was also kind enough to give me a few felt dealer's trays around the same time. I use them for my junk box coins, using one of the trays flipped over as a dust lid.
I use
flips on all my other coins, preferably like the ones
Forum uses.
Flipping an empty tray bottoms-up would be an easy, low-tech solution to the problem.
