11th century silver coin [επιλυμένο]

Recently acquired in a lot came with a card i can't read.

The diameter is ca. 20 mm

And its  0.5 g

 My guess would be Austria. 

N#162103 

N#190631 

 Both of them have a similar building on the reverse, with a tower either side. 

Also as the paper says Graz on it.

Hi,

The text of the card says:

"Halberstadt Bist.(hum)

Reinhard v. Blankenburg

1106 - 1123

Denar (???)

Dbg 633

gefunden in

Ehrenhausen b.Graz     S. "

Thus, it seems to be a coin (Denar??) of Reinhard von Blankenburg, who was between 1106 and 1123 Bishop of   Halberstadt (today Sachsen-Anhalt, Germany).

The coin was found in a village named Ehrenhausen near Graz, Austria.

Regards

 Well done. I added all that to the picture:
