wabnoles Posted June 3, 2013 Report Share Posted June 3, 2013 Hey there everyone This is something I did a while back to help me gauge coin sizes in terms of diameter, thickness, and weight. What I did was take the standard sizes of US small cents, dimes, nickels, quarters, half dollars, and large dollars. Here's what I got: Small Cent Diameter: 19.05 mm Thickness: 1.55 mm Weight: 3.11 g Dimes Diameter: 17.91 mm Thickness: 1.35 mm Weight: 2.5 g Nickels Diameter: 21.21 mm Thickness: 1.95 mm Weight: 5 g Quarters Diameter: 24.26 mm Thickness: 1.75 mm Weight: 6 g Half Dollars Diameter: 30.61 mm Thickness: 2.15 mm Weight: 11.5 g Large Dollars Diameter: 38.1 mm Thickness: 3.1 mm Weight: 26.73 g Quote Link to comment Share on other sites More sharing options...
rsraghead Posted June 3, 2013 Report Share Posted June 3, 2013 That will be a useful guide for many Quote Link to comment Share on other sites More sharing options...
Art1.2 Posted June 3, 2013 Report Share Posted June 3, 2013 Nice for determining the approx size/weight of other coins. Quote Link to comment Share on other sites More sharing options...
wabnoles Posted June 3, 2013 Author Report Share Posted June 3, 2013 That's what I was thinking... its easy to determine or guestimate a coin size when you are getting it from a store but it is a little difficult to fully grasp the size if you are buying it off the internet and are trying to look it up online. For instance I know my Guernsey 4 Doubles I just bought is a little larger than a standard US quarter. Quote Link to comment Share on other sites More sharing options...
thedeadpoint Posted June 4, 2013 Report Share Posted June 4, 2013 I motion that we add imperial/standard values to this and pin it in one of the forums for an easy-to-find, quick reference. Quote Link to comment Share on other sites More sharing options...
rsraghead Posted June 4, 2013 Report Share Posted June 4, 2013 That sounds like a very good idea Quote Link to comment Share on other sites More sharing options...
HarveyJMartha Posted June 4, 2013 Report Share Posted June 4, 2013 Oh Wow!!! Thanks for the details. Now that fakes are on the rise, this information should be of great help. Quote Link to comment Share on other sites More sharing options...
Trantor_3 Posted June 4, 2013 Report Share Posted June 4, 2013 Oh Wow!!! Thanks for the details. Now that fakes are on the rise, this information should be of great help. A little warning here: the small cent is listed here with a weight of 3.11 g. But, there are cents with different compositions, which do not all weigh the same, a cent can also weigh 2.5 g (copper plated zinc), 2.7 g (zinc coated steel), 4.67 g (copper-nickel) Same goes for the other denomnations: an other composition may mean an other weight.

wabnoles Posted June 4, 2013 Author Report Share Posted June 4, 2013 Sorry I should've added that clarification... yes you are correct. The small cent I am using is the pre-1982 95% copper cent; the dimes, quarters, half dollars, and dollars are all pre-1964 90% silver weights; and the nickel is the non-silver 20th century variety, which I believe is the same weight. In other words, the weight reference is more in line with the kind of coins we are collecting rather than handling on a daily basis. Quote Link to comment Share on other sites More sharing options...
rsraghead Posted June 5, 2013 Report Share Posted June 5, 2013 That just means wee need to make a bigger list. Everybody working together and adding info it would not be a problem Quote Link to comment Share on other sites More sharing options...
