undated medieval coin without lettering a mystery [решено]

Former owner said he thought it was Salzburg, but no denomination or lettering to check or medieval book to look in. I can not do photos but drawing is very accurate, probably a bishop with crozier and cross or scepter, with 3 crosses on reverse. Could be protestant or Catholic. No scale so could be bilion, and is about the size of eastern European denar. It's likely a Bistum or bishopric issue rather than stadt.

Hello and welcome on Numista.
Without having its weight and pictures of it, we can only make assumptions.

Pictures seem accurate for you but some elements of the coin could have been misinterpreted or are not represented on this drawing at all

If it's Salzburg, I assume it's most likely a stylised castle on the reverse side than a serie of crosses.

Does it look a bit like that ?

Regarding its diameter it's most likely a heller, but we can't be sure without its weight : it could be a small pfennig too.

If it's not Salzburg, I can propose this one https://en.numista.com/catalogue/pieces132725.html

to Cycnos,
I'm pretty sure that you are right. It is a Weissenburg coin. Having the Abby's name I found in Craig that they made denars in the 11th - 13th centuries, and my coin is about the right size. My reverse is of a castle with 2 towers. I missed that. But I am sure that there is a large cross in between. I also guessed wrong about the miter. It is a crown. Small differences on the obverse I just ascribe to varieties from different engravers and ages.

I can't believe how fast you ID'd my coin. No date, no lettering, an inaccurate picture, and you find a coin from an Abbey the size of a small shopping mall in a place I never heard of,that hasn't made that type of coin for 700 years. I am impressed.

Thank you very much.
