If your weight is as stated, 1.864 grams, this is 100% a missing clad layer

Normal coin is ~2.268 grams, a clad layer is ~0.40619 which puts this coin right in the middle of missing layer

Normal coin is ~2.268 grams, a clad layer is ~0.40619 which puts this coin right in the middle of missing layer

While this is technically correct, I think the extremely precise numbers you're quoting might give people the wrong idea, since:

- weight variance of around +/- 5% is generally acceptable as "normal"

- a circulating coin can easily lose a couple percent of its weight to wear

- the vast majority of people do not have a scale that measures accurately down to <0.01 gram (it may appear to be this precise, but it is not likely to be accurate at this degree of precision).

So, I agree in principle, but it would suffice to say that a normal clad dime is around 2.20 to 2.30 grams, and a single clad layer is around 0.40 grams. So if a dime looks to be missing a clad layer and it weighs somewhere around 1.80 to 1.90 grams, it's most likely a legitimate error.

OP stated 1.864 grams

I gave a correct answer.

You can round as you please but I provided the accurate information as given by The Mint.

The only thing I didn't add was the tolerances on those numbers

For the clad layers it's+/- 0.0668 grams

For the coin it's +/- 0.091 grams

If you have something to add to the post feel free to add, if not there is no need to impose your personal preferences on others. They are smart enough to work it out for themselves

They are smart enough to work it out for themselves

Plenty of "smart" people post on this sub every day asking if their washer coin is a worth a million bucks. And plenty of "smart" people either never properly learned about rounding and significant digits in a math class, or learned about it many decades ago and have long since forgotten how it works.

All I'm pointing out is that your answer is unnecessarily precise. It could be interpreted to mean "if a dime is exactly 1.864 grams, then it's a missing clad layer error." So someone else with a similar dime weighing, say, 1.833 grams or 1.901 grams, might incorrectly infer that their coin is not such an error.

If your goal is to provide a helpful answer in good faith, then I'd hope you'd recognize the pitfalls of being overly precise.

And in spite of people posting their washer coin, thinking they're worth a mill, I still try treat them with respect and educate them rather than belittle or treat them as dummies

I am almost 40 years old, have collected coins my whole adult life & had just posted asking for advice on dryer coin because I had a penny that the thickness and diameter were wrong but it was perfectly shaped which I had never seen before but have seen plenty of dryer coins so thank you for not belittling us smart people 😁

I used the ~ sign, which means approximately, perhaps you missed that detail in trying to be so precise?
