To sum up, the definition of numerology can be said as follows: numerology is a discipline that studies coins in a cultural sense. Including the study of real money, but also the intangible culture contained in real money, or the intangible culture behind money.

The purpose of numerology is to carry out scientific research on coins from ancient times to the present. First of all, we should identify its authenticity, make a true and correct judgment on its historical value, scientific value, artistic value and social significance, and then carry out relevant intangible cultural research on this basis. In this sense, coin identification is the basis of numerology research, or the basic skill of numerology research.

In numerology, money should be the general name of money and its cultural derivatives. The main body of money is money. As soon as money was born, the "derivative" of money culture followed, and with the footprint of money, it also evolved and developed with money. Although they are the twin brothers of money, they can't exercise the function of money. They are closely related to national culture and folk culture, or they are the products of national culture, folk culture and money culture.
