How to distinguish the authenticity of a set of map coins from 1949 to 1955 issued in Taiwan Province province, especially silver coins? Can you see if the coin has passed?
The authenticity depends on the face value of the map of Taiwan Province Province on the back of the coin. Sun Yat-sen's head can be seen in the words of Taiwan Province Province, and concave shadows can be clearly seen on aluminum coins and silver coins. If not, it's fake. These two expensive varieties may be fake, and the others are not very expensive. Generally, there will be no fakes. I also like to collect map coins of Taiwan Province Province and share a set of map coins.
