...if it was from the time the casino was "Grand Casino Lac Courte Oreilles" (1989 to 1993), or "Lac Courte Oreilles" (1993 to 2018). Probably the latter, though maybe not. All remaining chips were privately purchased from the casino when its name changed to Sevenwinds, and I don't recall a single special chip from a band performance being in the bunch, and you would think there would be at least one?
