| Making your counterfeit detection specific gravity test
If you're an ANA member, a great article on how to make your own specific gravity test to figure out metal content of a medal, token, world issue, or U.S coin or pattern.
You can view the article online here if you're an ANA Member, or page 98 of the ANA magazine. It is the july 2009 verison
