Taiwan Fifty NT Dollars (Yuan) 2005

The current issue Taiwanese fifty NT dollar coin was introduced in 2002 to combat the proliferation of counterfeits of the earlier bi-metallic issue. As well as having a front facing effigy of Dr. Sun Yat Sen on the obverse, the reverse contains a "latent image" of the denomination. When viewed one way the numerals 50 can be seen, viewed from another angle the Chinese characters for 50 are seen. Similar technology is also found on the Japanese 500 yen coin.
