That applied to the single piece; the overall tolerance (for a large quantity of coins) was basically zero.</p><p><br /></p><p>Today&#039;s euro and cent coins, for example, have more &quot;flexible&quot; limits: For planchets that are nominally 2 mm thick, there is a thickness tolerance of 2%. The weight tolerance is 3% per piece, and 1% per 100 pieces ...</p><p><br /></p><p>Christian[/QUOTE]</p><p><br /></p>
