Small silver coin - Quarting ¼ Denar - Zsigmond 1387-1437 [решено]

Hello,
Reminds me from it's style this one: https://en.numista.com/catalogue/pieces88085.html
But may be something completely different.
Obverse: crown
Reverse: two-armed cross with the letters K ans S
0.57gr
11X14mm

I looked at the "double cross" of Lorraine, then of Slavonia then I found this
Medieval Hungarian Coin - Wladislaus Silver Denar KM With Double Cross
or Medieval Hungarian Coin - Wladislaus Denar WB With Double Cross, 1440-1444.
or this other one

Thank you, that link got me to that coin : http://www.ebay.ca/itm/European-Midieval-Silver-Pfenning-Penny-Foliated-crown-Obv-Cross-Re-lotoct8828/401216964877?_trksid=p2047675.c100013.m1986&_trkparms=aid%3D555012%26algo%3DPW.MBE%26ao%3D1%26asc%3D39923%26meid%3D66bf680de1344ab1b99e92fa37d2cfa6%26pid%3D100013%26rk%3D1%26rkt%3D12%26sd%3D272384165804
It looks quite similar but unfortunately doesn't seem to be identified...

4x Quarting ¼ Denar - Zsigmond 1387-1437 = 0.57g ?

Quarting should fit

Perfect!
Thanks a lot.
