Russian Empire coins question - Polushka and Denga [gelöst]

I have two coins that I think are a Polushka https://en.numista.com/catalogue/pieces17730.html
and a Denga https://en.numista.com/catalogue/pieces11217.html

However, my coins are different than the ones in the pictures. If you look at the bottom of my coins, the Denga has straight crossed lines and the Polushka has a pretzel-like knot. Does that matter? Is the lettering the important part and the rest normally has design variances?
Thanks!

This is what my coins look like:

These coins are hammered.
So every year a new die is made (also by hand)
It is not a wonder that your coins does not fit exactly, that is impossible.
Even for the same year different dies are made. If one is worn, a new is made.
Do not worry about your coins, the look genuine.
Nice coins!

That makes sense. Thanks!

There are more than 10 types of each of your coin (of one year), minted in Moscow and Ekaterinburg. You have both from the Ekaterinburg mint.

Thanks!
