You have probably asked yourself how coins get their market value and what determines their authenticity. It is interesting to know that grading became a usual practice in the U.S. since the mid 19th century, when coins first started being collected.

Assaying was a common practice when silver and gold coins, like the renowned silver half-dollar, used to be in circulation. Most countries, including the US, do not circulate full silver or gold coins for regular spending, yet the assay process is still essential in the creation of their precious metal bullion.
