Need help with Qing cast cash [resuelto]

Hello! Need help with these coins because not sure in authenticity. First one looks a bit strange to me, second have error in manchurian mint.
 

N#12421 , Hartill#22.598
and 

N#26024 , Hartill#22.578.
Not sure what kind of error you're talking about, the coin looks normal to me. 

I mean the head there, and then first one good? Thanks for help!

If you mean that the top part of the mint name, that's not a huge deal.

Probably the molten metal just didn't fill up the space perfectly. There are other parts on the coin, where the casting was subpar. These are just small imperfections, not really errors, a lot of coins have those.

The first coin also looks good, just a little bit worn.

Thanks for help!
