Good Day - When reading some literature on Canadian Silver dollars, I often see references to the physical size of our silver dollar, to include diameter, weight and thickness. With respect to the thickness values, how does someone "measure" the thickness of a silver dollar? from or "by" the rim thickness or the fields?

Thanks in advance

By the rim.It varies more than weight or diameter,not a useful measurement unless the coin is under or over weight by a significant amount.
"Dipping" is not considered cleaning...

vernier caliper will be usefull. However, by weight, look, magnet, you will rid most of fakes

DBM - Thank you for the information. That is why I asked the question to begin with. My measurements varied quite a bit. Basically from 2.7mm to 2.9mm.

Thanks again

MJT - thank you and good point. I am even measuring specific gravity (relative density) to eliminate, in my mind, any potential fakes. luckily none have been found yet in my modest collection. "Look" is a difficult characteristic to copy, thankfully.
