Do coins have to be in the same year to be divination?

You don't have to use coins of the same year to calculate divination, you can use coins of any year.

Divination is a superstitious behavior, and there is no scientific basis to prove its accuracy. Therefore, when calculating divination with coins, we should choose the appropriate coins according to our own experience and intuition, rather than relying too much on the year.

It should be noted that using coins to calculate divination is only a psychological suggestion and prediction means, and it cannot completely replace scientific methods to solve problems. In the face of difficulties and problems, we should actively seek scientific solutions and treat fate and life rationally.
