The modified banknote has the same dimensions and general design as the 50-ruble banknote of 1997. The banknote colour design has been changed insignificantly. On the front of the modified banknote in the lower part of the unprinted area to the left of the main image there is a text “МОДИФИКАЦИЯ 2004 Г” (2004 modification).

The modified banknotes have the following main differences:

  • the protective fibres of three types are embedded in the paper (red, light-green and two-coloured);
  • the metallic window thread is embedded in the paper. It comes out on the surface on the back of the banknote;
  • on the front of the banknote there is a field with latent coloured waves (MVC effect) - moiré variable color (MVC);
  • on the front the numeric value of denomination is printed in grey non-metallic ink;
  • images of the banknote under an ultra-violet and infra-red light have differences from the banknote of 1997.

  • Multitone watermark

    The paper has local watermarks on the left and right coupon fields. In the wide coupon field there is the Peter and Paul Cathedral in St. Petersburg and in the narrow coupon field there is a numeric value of the denomination (value numeral 50). When the banknote is held up to the light you can see various parts of the watermarks, some of which are lighter while others are darker than the surrounding paper.

       
  • See-through (printing in) register

    The note is printed with great accuracy so that irregular elements of the design on both sides of the banknote join up to form a complete picture when the banknote is viewed against the light.

    “Windowed” security thread is a metallized plastic stripe embedded in the paper. Some parts of the security thread appear as a series of silver dashes on the paper surface on the back. When the banknote is held up to the light you can see the security thread as a straight continuous dark line.

  • Micropattern

    On the reverse side of the banknote there are images consisting of fine lines that look like an even background for a naked eye. Copying these images causes their possible distortion or appearance of inappropriate light or dark images (moire effect).

  • Latent multicoloured waves (moire variable colour (MVC))

    When a banknote is viewed at the right angle the area looks one-coloured. When the banknote is tilted you can see multicoloured stripes on that area.

       
  • Latent image of the letters „РР”
    (kipp-effect)

    When a banknote is viewed at an acute angle, letters „РР” become visible on the decorative stripe. The letters become either light on a dark background or dark on a light background depending on the orientation of the banknote.
