You might also be able to make a "wallet" or "pocket" to gang scan, then separate them in an editing software, like Pshop (you don't say whether you have that).
I set up a roll fed scanning operation for a company, and for items too small to feed into the transport system, I took very thin mylar (maybe 2mil?), hinged to translucent mylar, or paper material and positioned the small things together, making one large scan. You can also make smaller pockets for one item at a time.
Issues might be focus, depending on the scanner, you will need to crop somehow, as the scanner will likely define the shape as the whole pocket. All depends on your work flow.
The pockets also become abraded or smudged over time and have to be remade.
