Currency King 7950: the currency king in foreign exchange certificates seems to have a special relationship with the four editions of coins. The fourth edition coin 8050 is the king of money.

The circulation of 7950 foreign exchange certificates is only about11million, and it was replaced by 8850 in just ten years. The important reason is also the appearance of false certificates. At present, it is estimated that there are only 40,000-50,000 pieces in the world, and there are very few good products, which are full sets of foreign exchange certificates.

The price of the whole product 7950 is above 1500, which is very rare, and the price can reach above 4000. It can be said that the number of surviving 7950 is much less than that of the fourth edition of 8050, and even less.
