 United States Coin Information

 Published nominal coin weights for freshly Minted US coins can be found at the US Mints web site.
 Though not listed here, the tolerance for a single coin is typically +/-3%. Accuracy can be improved beyond +/-3% by averaging the
 error from a number of coins. In this case, error goes down by the square root of the number of samples used. Therefore, if the
 sample size were 16 nickels, the average error would be 1/4 as or better than +/-1%. This is pretty good, except that some coins
 may be worn.


 Notes:

 The composition of dimes, quarters and half dollars before 1965 is Silver. These weights are not listed.

 Note:

 The penny weight is specified as 2.5g +/-0.1g. However, unlike the Nickel which has not changed since 1938, the penny was
 changed in 1982 from pure copper to zinc with copper cladding.

 Precision Weight Scales

 If you are looking for a good quality and not too expensive precision scale from a company with a good reputation, the
 DuraScale 100 or DuraScale 50 are good choices. These scales have total weight capacities of 100g or 50g, respectively, and
 both are rated at +/-0.01g accuracy.
