wow - weird - ATS 12 yrs ago, someone shared this; an 87-D rolled thick planchet, but weighing 5.7 g
and then, on another forum a couple yrs ago, someone says this as a response to someone asking about a nickel weighing 5.3-5.4 g
"Scales which weigh to 2 decimals in grams are more helpful. Those which weigh to only one decimal leave room for inaccuracy because of rounding. Expected weight is 5.000 g +/- 0.194 g This coin may be on a slightly rolled thick planchet. The likelihood is that it is not rolled thick enough to be collectible. Expected thickness is 1.95 mm +/-0.102 mm. If the thickness of the coin exceeds these parameters then it would be considered collectible. (Cited from: https://www.cointalk.com/threads/just-a-heavy-nickel.351408/)"
do you have digital calipers to measure thickness of your nickel?
No but I think I will invest it definitely weighs 5.3. It's strange that these are both 1987
can you sandwich between a couple of regular nickels and take a pic for us?

smart way to 'measure' the thickness 💪🧠
In most cases a thick rim is just a sign of a well struck coin (check out proof coins).
@Zoee What's a "nickle"?

Does it weigh 5.2 or 5.3 on your scale?
As stated earlier, the weight tolerance is +/- 0.194 grams, so a nickel weighing 5.194 gms is in spec. If it weighs 5.2 gms on a level, calibrated scale with a 0.1 gm resolution, it may or may not be out of spec. Even if it's overweight by a few hundredths of a gram, it would be a very minor error and not add any extra value
There are smart people on this board. Not all of us mind you but many.

Hello I also have found a beautiful 1987D nickel that weighs 5.2. My scale is accurate. My other nickels weigh 5.00grams
Within tolerance
All comments reflect the opinion of the author, evn when irrefutably accurate.
You have to coins to two decimal points.
5.2 g could easily be 5.17 which would be within the tolerance of 5.19g
Also - tolerance is not specified generally in the law, especially for minor coins (Secretary's discretion). And generally, tolerance has a percentage attached to it, allowing for some percentage of pieces to be heavy or light.
If you take 0.194 to be 2 standard deviations (a normal distribution will have 95% of items within 2 SD plus or minus around the mean - this is a slight fudge, but commonly used)... 99.7% will be within 3 standard deviations (or 0.291g) and thus out of 1,000 coins...
950 will be between 4.709 and 5.194
a further 23.5 will be between 4.612 and 4.806 and 23.5 between 5.194 and 5.291.
3 will be under 4.709 or over 5.291...
With those #s you cannot say the process is out of control. Now any given sample of 1,000 coins might have a different distribution - it's only mathematically value for the entire population.
For precious metal coins, the tolerance isn't actually specified either, but a floor is given - so you never get a short-weight gold coin.
