Yes ... that.
Nickle has about 4 times worse electrical conductivity compared to
copper, and the skin depth at 30 MHz is about 20 times thinner (about 12
microns for copper versus about 0.65 for nickle). ChatGPT tells me that
standard nickle plating is roughly 5 to 10 microns thick , and that even
low cost nickel plating is typically 1 to 2 microns thick.
The math agrees with you.
I wonder if anyone has made measured comparison of his coils versus a
similar copper one.

I would need some convincing that nickle plating is a good idea.

Hello,
If any of y'all are in need of any inductors (or loading coils) for
your 80
or 160m verticals, my good friend Gaylord Gasque, N6SF, has started
manufacturing several models.
I have tested several of these at my QTH. I really like the ones
with the
built-in mounting hardware he calls the Q-Coil furniture.
With B&W and MFJ no longer marketing coils, Gaylord took it on
himself to
supply the amateur community.
His website is https://Qcoil.net <https://qcoil.net/>
I hope you'll check it out.
