These generic poker chips are more modern and not as nice as those other plastic-like chips in this thread, but they are a relatively new find. They are sturdy, strong poker chips, and were coded PLMI-Maple Leaf in the 2001 supplement to the book. I'll sell three (red, white and black) for $7 total, post paid. They are an emblem of Canada, so fitting that they were made/distributed by R D Fleck and Co, Toronto Canada. Like other old coded chips that look like plastic, these are interlocking and the inside of the chips are granular, so you could call them composition if you like.
