A system and method for securing tokens to be cleaned includes a tray with a curved surface defining a channel extending along a first direction and spacers projecting from the curved surface into the channel. The spacers are disposed at regular intervals along the first direction. The curved surface also has at least one opening. The tokens may be inserted into the channel between adjacent spacers and the tray holding the tokens can be submerged into a cleaning liquid. Identical trays containing tokens can also be stacked and together submerged into the cleaning liquid. The tray holding the tokens can be placed on a drying surface that has a drainage hole, and wetness remaining on the tokens can be sucked through the hole in the channel and the drainage hole by a vacuum or blown through the hole in the channel and drainage hole by an air blower. |
