Shown below are the roulette chips for the Koningsdam. From a visual perspective standpoint, this image shows a clear plexiglass shelf over the stacks of roulette chips. On top of that shelf, and fully exposed to people walking by, are the different colored roulette chips on a clear plastic display stand.

They did not sell used playing cards, explaining that "COVID" prevents them from doing so. (But "COVID" had nothing to do with players touching cards is some of the table games.)
