This SCAD script allows you to print mulitple numbered coin tokens meant to be drawn at random from a bag. There are lines over the top of the number to make it more difficult to feel around for a specific number. To change the number, modify the last line of code to include the desired number. Then take the code to https://ochafik.com/openscad2/ and download it as STL, then slice it with your favorite slicer. It should be able to be printed at any size required, without needing any supports.
