Seems like these two coins are doubles. They are from the same material and size, just two different mints. We could merge them into one and add different mint marks for the years.
Same with these two:
And these as well:
Also the same is with a lot of those Russian coins, from ~1750 to ~1860
Should we merge each type into one page, because seemingly there is a single page for the mint mark variations, so we could just add them to the year lines. I could just add date lines to the one page to the other and delete the other page. I have time and could do that
