Twenty years ago at a Origins in Baltimore, I purchased a bunch of plastic stands which held standard sized chits vertically. They were designed for semi-hidden movement. The backs were black so the opposing player couldn’t see what they chits were. The bases were small hexes and they were stackable.
But I have no idea who made them, or if they are still available today.
My suggestion would be to make a color photo copy of the chits, cut them out and then glue them to small squares of wood, such as those found in the woodcraft section of the ladies’ craft stores. You could do the color photocopies for less than a buck a sheet if you watch for sales at the office supply stores.
