South Korean Won - Second South Korean Won - Banknotes - 50,000 Won Security Features

50,000 Won Security Features

1. Holographic strip (Optically Variable Device): The holographic strip is a special film applied on the left end of the obverse. On the top, middle and bottom of the strip, are three sets of changing images : 1: a 'map of Korea', 2: a taegeuk ('a two comma roundel'), and 3: 'the four trigrams'. When the banknote is tilted, each of them appears in turn. Between the sets of changing images, the denomination, “50000”, is printed vertically on the strip.

On the left top and bottom of the holographic strip, against a background of geometric guilloche, the words “BANK OF KOREA 50000” are printed vertically. A line of a Korean traditional lattice pattern is embossed on the strip's right end.

2. Moving image security thread ("Motion"): The 50,000 won note has a special blue and gray film with numerous Taegeuk patterns all over it. Taegeuk patterns move to the left and right when the note is tilted up and down, while moving up and down when the note is tilted to the left and right. When the note is held up to the light, the movement of the Taegeuk patterns appears more clearly.

3. Novel numbering: The sizes of the digits (numbers and letters) used in the serial number increase gradually from left to right.

4. Color-shifting ink: The color of the face value number (“50000”) on the top right of the reverse turns from magenta to green or from green to magenta, when the note is tilted.

5. Watermark: Held up to the light, a hidden portrait (of Shin Saimdang), produced by using the variation in thickness of the note paper, appears in the non-image area on the left side of the obverse.

6. SPAS: Special Press and Soldering: SPAS is a kind of watermark, produced using the maximized thickness variations in the note paper. It is located on the right bottom of the watermark and if you hold the banknote up to a light source or look at it with the naked eye, the number ‘5’ appears within the pentagon.

7. Intaglio Latent Image: If the note is held horizontally and tilted at eye level, the number ‘5’ appears within the intaglio-printed pentagon.

8. Security thread: If the note is held up to the light, the micro letters “한국은행 BANK OF KOREA 50000” is printed within a special film hidden on the right side of the portrait.

9. Intaglio Printing: Granular texture can be felt when touching the portrait of Shin Saimdang, the Wolmaedo painting, letters, five lines of tactile marks and denomination numbers.

10. See Through Register: When the note is held up to the light, the round images on the obverse and reverse are combined, appearing as a two-comma roundel (Taegeuk).

11. Endless Pattern: Exact identical patterns are printed at the same places in the top and bottom and to the right and left, around the edges of the note. If the banknote is folded and connected to the top and bottom or to the right and left, the patterns overlap.

12. Rainbow Printing: To heighten the counterfeiting deterrent effect, a special printing method for mixing colors naturally in areas shared by two different colors is employed.

13. Fluorescent Security Ink, Fluorescent Security Fiber: When the note is illuminated with ultraviolet light, fluorescent green (security ink) on the grape painting and short fluorescent red, blue and green lines (fluorescent security fibers) show all over the banknote.

14. Filter Through Latent Image: Through a specially-produced filter, we can observe the hidden face value number “50000” in the non-image area of the reverse.

15. Micro Lettering: Intaglio-printed micro letters (consonants of Korean alphabets and “BANK OF KOREA”) and offset-printed micro letters (“50000”) can be discerned with a magnifying glass.

Famous quotes containing the words security, won and/or features:

    It is hard for those who have never known persecution,
    And who have never known a Christian,
    To believe these tales of Christian persecution.
    It is hard for those who live near a Bank
    To doubt the security of their money.
    —T.S. (Thomas Stearns)

    Passing away, saith the World, passing away:
    Chances, beauty and youth sapped day by day:
    Thy life never continueth in one stay.
    Is the eye waxen dim, is the dark hair changing to gray
    That hath won neither laurel nor bay?
    Christina Georgina Rossetti (1830–1894)

    Art is the child of Nature; yes,
    Her darling child, in whom we trace
    The features of the mother’s face,
    Her aspect and her attitude.
    Henry Wadsworth Longfellow (1807–1882)
