Tolerance. Same as mint remedy ; the extent to which coins may be abraded (reduced in weight
by abrasion) or otherwise worn and still be redeemable at the Treasury at their face value.  The
law says that any gold coins of the United States reduced in weight by natural abrasion not more
than 1-2 of I per cent after a circulation of twenty years, as shown by the date of coinage, and at a
ratable proportion for any period less than twenty years, shall be received at their nominal value
by the United States Treasury.  The tolerance on silver and base metal coins is unlimited; the
Treasury will receive them at their face value until abrasion or wear has obliterated the inscriptions
on them.  The term tolerance or mint remedy also applies to the allowance for a slight difference in
the fineness of gold or silver from the government standard. In gold the limit of difference above or
below is one-thousandth; in silver it is three-thousandths.
