No. The obverse legend clearly says this is a coin of the Grand Duchy of Hessen (GROS HERZOGTHUM HESSEN). So this is the only possible issuing authority, meaning you can constrain your search to coins from this place.
All the details are 100% consistent with the type linked by @bjherbison, which was minted 1838-1842.
You will be able to find many other 1812 3 kreuzer coins from German States (Nassau, Baden, etc.) but none of these can possibly be correct.
Cita: "Rdolce"I can see your point.
But it says 1812.
3 people including myself can see the date in person and conclude date is 1812. Is it a mistake in date.
Thanks for help

Your last two pictures are still blurry, but the digit looks like a "4" to me. The slant at the top seems too long to be a "1" and I see a shadow of the cross-bar on the right.
It has to be 1842 from that last picture - there is too much space on the
right of the 8 as the gap 1 8 on the left would be repeated on the right 1 8 1 but it
is not - more like 1.8..1 so there is room for the left-hand part of the number
so is 4 there. Hope to have explained properly.
Yes. From that last image I made these ...
1. Green is visible parts - so does not look like the 1 before the 8
and the white lines are equal spacing - showing the longer space after 8 number.
2. Cropping the picture to make all spaces the same to show what 1812 would be.
So cannot be 1812 date.
Agreed. I made this ...
where the space for a wide 4 is the same, as the 2 at the end does not move.
It would move to the left if there were a narrower 1 there instead of 4 number.
Apart from all that, it was mentioned earlier that 1812 coins did not have that
shield and crown design on the other side. So 1842 it is.
Yes it was an 1842 coin that only the 4 was significantly worn or was intended to be a 1842 coin but due to die error was not completely. Pressed. I tend to believe the latter .
