Please help ID Hungarian Denar

Hello,

can someone help me ID this Hungarian Denar?
To the sides of Saint Mary with Baby Jesus I see the letter B and to the right the letter S? (Not sure on the letter to the right.
Sorry the coin is very worn.

Metal: Silver
Weight: 0.49
Diameter: 16mm



Thank you,

Paul

Oops sorry, forgot to add them

In the middle of coat of arms it looks like bird - raven, in that case it is a denarius of Matthias Corvinus:

Thank you Leonidas, you are probably right with Matthias Corvinus.
Must be not the exact same one as on the Numista link its a gothic N on the left and on mine it seems to clearly be a B
I will try to check past auction results to see if I can now find a match.
