silly question - Is your scale calibrated?
Courtesy is the one coin you can never have too much of or be stingy with.

Coin collecting is the only hobby where you can spend all your money and still have some left.

One possible explanation is that your coin is not 0.925 silver KM#6a (which according to Krause should weight 25.7 g) but copper-nickel KM#6. Though Krause doesn't bother to give the weight of the copper-nickel version, I've seen it before with other crown-sized modern coins - the non-silver versions are significantly lighter.
Look at the color of the coin (it's difficult to judge by your picture) - silver versions are usually more whitish-silverish whereas copper-nickel versions are usually a bit darker with "nickelish" color to it.

​I've just checked several older editions of Krause but there isn't any edition where the weight of the copper-nickel dollar is mentioned. I also can't find it anywhere on the internet. So I don't know where the weight of this coin in our catalog comes from, it might indeed be wrong.
I only have a silver dollar, not a copper nickel one so I can't check it, but as you can see here (https://en.numista.com/catalogue/pieces3397.html) Andrey78 has one on his swap list. You can send him a message and ask if he can weigh his coin.
