To determine if a poker chip is real, examine its weight and feel; authentic chips are typically heavier and made from high-quality materials like clay or composite. Check for a smooth, consistent surface and a clear, vibrant design, as genuine chips often feature intricate details. Look for a specific denomination or branding, as real chips usually have identifiable markings. Additionally, inspect the edges for a sharp, defined texture, which indicates quality. Finally, if possible, compare it to known authentic chips to spot any discrepancies in size or design.
