1 złoty 1794 - dangerous forgery

Very well done forgery of one of the rarest Polish banknotes. Made on handmade paper with chemical security sign properly reproduced. The obverse does not raise as many objections as Malinowski signature on the back that is much thicker and less carefully reproduced than the original. Several years ago a similar piece was sold at foreign auction for several thousands zlotys (described as genuine!).
