IM looking for opinions on this 1966
Roosevelt dime.. The dime only weighs 1.6 grams. I can't seem to find anything on a foreign planchet weighing 1.6 /1.7 grams and when I do the light drop on my table I get the same ping that I get out of my silver
Mercury dime. Until I get it tested, I'm going to assume it has silver. Any Ideas?
