Watermark Error - Indonesia Banknote Rp 50, 1960.

Hi, I'm from Indonesia. has one type of 50 Rupiah note from 1960, with the front picture of President Soekarno and the female dancer on the back. This money has the Bull's Head watermark above, usually slightly below. can anyone tell me is this watermark normal or unusual?? My search results have not found anything similar for the same money. Please help…tell me how much this money is worth….anyone?????

Generally, in my experience, watermark errors aren’t worth much more than their regular counterpart. I would value it at ~10% more than regular value.
