The modified 1000-ruble banknote from the 1997 series, updated in 2010, maintains the format and design elements of the 2004 modification, with some minor changes in color.
On the front side of the modified banknote, in the lower part of the wide coupon field to the right of the main image, the text “MODIFICATION 2010” is displayed.
Key differences in the 2010 modification include:
- The paper contains two types of security fibers: bi-colored and gray.
- A wide security thread is embedded in the paper, featuring a window in a decorative shape (“stained glass window”) on the front side.
- A combined watermark is located on the wide coupon field.
- The coat of arms of Yaroslavl is printed in green using optically variable magnetic ink (OVMI), creating a bright, shifting stripe effect.
- Thin tactile lines are present along the edges of the coupon fields on the front side.
- In the lower part of the field with hidden moiré stripes (MVC+), there is an element with visible colored stripes.
- The height of the digits in the left serial number gradually increases from left to right.
- On the reverse side, the multi-colored ornamental stripe has been modified.
- Some elements of the design have magnetic properties.
- The banknote’s appearance under ultraviolet and infrared light differs from previous issues.
The banknote features two serial numbers on the front side, consisting of a two-letter series code and seven digits.
