15mm medieval Europe (?) silver coin with crest [solved]

Thanks in advance to anyone who can help me improve the attribution on this 15mm coin weighing only 0.7g. I think it was base silver or possibly silvered.

It‘s obviously seen better days, but I’m hoping someone will recognize the crest (seems to have a B in the center) and the familiar reverse. Thanks!

Second image looks like PATRONA on right side.

Hungary. After 1500.

One of examples.

Search in catalogue that you can tune further is below. Add silver filter, size or weight. Note that some entries might not have size or weight set and filters will not work for them. You might go further in the past or future, but as far as I know before 1500 coins were not that round or used different designs. Silver content might be below 50% and composition might be classified as billon.

Try figuring lettering instead of coat of arms.

This is a contemporary counterfeit of a Hungarian denar that had been in the ground most likely you can see that this had silver plating.

This is a contemporary counterfeit of a Hungarian denar that had been in the ground most likely you can see that this had silver plating.

Also this has K and B on either side of Mary and Jesus (aka madonna) meaning the maker tried to pass this off as a Kremnica mint denar

Thank you both!

It does look like the denars of Rudolf.

And a contemporary plated imitation would certainly explain the condition.

Thank you!!
