Has Anyone Any Information On This Counterstamp?

Anyone that knows my collecting preferences might recognize this type coin from another thread. I am the buyer and did so because I want to check something in addition to the odd chop mark that looks like a bird? over four I's or 7's.

I do not think the chop is Chinese. Looks like one of the eagles from a German State or possibly eastern Europe. I agree it is not really clear in the sellers pictures.

I will try to get a micro-photograph when the coin arrives.

As a clue yo my earlier questions, look at the shield and at the test cuts on the King' head. Notice anything odd?

jgenn Yes, exactly. That is an early version of the keyhole porthole window type struck before the right window was fully eroded into a circle. As I have said before I believe the issue was a contemporary counterfeit using various debased planchets. It is a variety that is very well represented in TPG holders.

I am hoping that finding the origin of the c/s might shed some more information on when and where this variety came from.

to the Community, chopmark, and thank you for your contribution!

Actually, I have no idea when this chop was in use. Few hard facts are known about chops (when and where they were made and by who) so it could have been any time. Also, the character isn't #30410 as stated in my previous post. That number is just on assigned by this forum's software as it doesn't appear to support Chinese characters (I originally wrote the Chinese character but it was changed into that number). Sorry I couldn't be of more help. Chops are a focus of mine but there is little actually known about the individual chops.
