oops-all-pfennig, tdziemia ,thank you both for sharing your opinion on the coin. Yes, it is a type coin ,from this time range. It was also very difficult , for me to decide on my own what is the last number.
tdziemia I think that you may be on the right direction here. I'm willin to agree with youre observation that it maybe 1614 , but here is a another guess- 1612.
At first it seeme to be a “5” ,but on a closer inspection I think it is either “4” or “2”, because it looks to me thath the last number has shorter base ,so maybe it is one of the two dates . I have also searched for a similar low qualit specimens on Internet but unfortunately I didn't managed to find
The quality is important as you mentioned , so I think that in this poor state the estimat you have pointed is a fair one.
Nevertheles , the coins from this period is still scarer for me ,from the one of the later period.
This is the first one which I have manage to aquire for my collection.
