A, what appears to be a complete reference guide for U.S. Coins and associated tolerances.

Well, the 3CS Type 2/3 is wrong, it's not 90% Silver and 210% Cu - that's a typo.

Thanks for sharing, good reference . Huh, never knew T1 3CS were only 75% silver. Goes to show how little I know about them!

Well, I just found it floating around the web, thought I would post it.
Maybe if I find time, I'll retype it from the jpeg into an excel sheet and fix the errors.. Being that I found it as a jpeg, editing it was not possible.

(according to CCF US Coin Facts the 1854 1873 is 90% silver but 10% Cu not 210%)

There are some other errors in there as well.
The second listing for flowing hair cents should be 1795, 1796
The copper nickel FE and Indian Head cent tolerance should be .259 not .130
The tolerance for the Washington quarter was .097 for 1932 to 1947, and then .194 for 1947 to 1964. 1947 comes both ways.
1947 Walking half early in the year tolerance was .097, later in the year it was .259

I copied this and sort of like it. May have some errors but then nothing of great importance to me.

Dearborn, I too have had a similar interest in a chart like this but mainly for the purpose of assisting me with Counterfeit Detection. The chart shown here gives the weights and measures and tolerance but that wouldn't apply to circulation wear. What I did was to make my own chart of the most popular series that I collect listing the weight, diameter and thickness of that particular coin. Next I weighed numerous examples in different grades and entered the info to my chart. While not foolproof, my chart seems to be quite handy when it comes to determining the weight of a genuine coin in any particular condition. If I weigh a coin and the weight seems too far off from what I have recorded, it sets off a red flag to me and further testing would be necessary. For example, I once had a 1921 Walking half in VG-8 that weighed half of a gram under specs from the RedBook. After weighing numerous walkers in the same grade, I came to the conclusion that the VG coins usually weighed 12.0 grams as opposed to the 12.5 grams in mint state. This helped me to conclude that the coin was genuine or at least not suspicious because of the weight. My chart is incredibly accurate when it comes to grading coins too. If I am on the fence trying to decide upon the correct grade, I can weigh the coin and compare it to the grades on my chart. It usually works out pretty well for me however as mentioned earlier, it is not foolproof. Morgan and Peace dollars can maintain their 26.73 gram weights in grades from mint state to XF-40. It isn't until they reach VF that there is a loss of weight. My chart is just another tool in my arsenal to assist in many ways. It only contains the various series that I collect though. On another chart I list the weights, diameters, thicknesses and specific gravity readings for almost every US coin except gold, Large cents, Two Cents and Three Cent pieces.

It's good to see others have the same frame of mind when it come to authenticity of a coin.

I have not yet had time to change the one I found into an editable Excel sheet. Then I can fix the errors that have been noted so far.
And the idea of getting measurements of worn coins is a great idea as well.

As mentioned, I made my own hand written chart but unfortunately I am still missing some data because I had no specimens in low grades to weigh, particularly in the Barber series. If any of you folks following this thread can provide the weight of your Barber halves, Quarters, and Dimes in G-4 and AG-3 that would be a big help to me. Once I can complete the data, I'll be able to post my chart that it may benefit the community as much as it has benefitted me.
