10 Pfennig 1916 - with no mint mark -- or I hope so :)

Hello,

Just to be clear, I just received my first over 100 coins from a far away relative.
I just got fascinated by them and I think I have some cool stuff here.

I read about the coin : 10 Pfenning 1916 - with no mint mark, has some value, maybe you guys can help me out - I don't even know if it's iron or zinc.
I had no prof camera, took the picture with my phone, if needed I will try to add a better photo.



This is my first add, if I did something wrong let me know.

Tkx for help !

Hello
I can see an F there  

Looks like that

I got confused too between KM#20 and KM#25 with my coin for a while  



But Then a simple magnet test confirmed that it's pure Iron. Also the weight matched with KM#20  

Hello,

Ty for answering. As you said, I can see the F, probably my mind didn't want to see it.

We all get like that sometimes! I had an 1860 farthing: I looked it up it was something like 2 grand in F, then I looked down and realised the second portrait one was worth £5...I had the second portrait one!

Yep, to be honest I got excited about it.
Took the magnet test, pure farthing.

But I found this   in the box of coins .. I am searching now



I find it hard to tell if a coin is F, VF or better coin ?
How do you people know this ? Btw I Googled a lot this, but from my point of view, a medieval coin in a slighty bad shape can be considered VF ? Am I taking this the wrong way ?

Ty !

All i know, it's a polish coin from 1500's .
I see a lot of these ,but it's quite nice though.

It is a Polish/Lithuanian Ort from the early 17th Century.

I think I would grade this as fine. I always find it helpful to find a picture of what the coin looks like in MS (or near MS) and judge the amount of wear from that.

That being said it is difficult, if not impossible, for one person to be able to very accurately grade every coin they come across. This is because they would need to know what the particular coin looks like in each state. Then eye appeal comes into play,  which makes coin grading fairly subjective...

Since medieval coins tend to have less detail,  it is difficult to judge 'loss of detail'. Is this coin worn? Or does this coin simply not have much detail? In your ort's case,  there is loss of detail,  but it has aged well and looks great for being around 400 years old.  Great find!
