First of all, we should understand the meaning of "star" in numerology. It is just a title, but it may actually be a different element. It may be represented by the shape of a star, two stars, a big star or a small point. There is no specific provision for this kind of expression, so we can't just consider this point when evaluating.
Secondly, whether Jiaqing Bao Tong's back star is divided into money or mother money, and whether it is a two-fold version or a three-fold version will affect its value. In addition, appearance is also an important factor affecting the price. If this ancient Jiaqing Bao Tong coin looks good, the price may be around 15 yuan; if it looks worse, the price may be around 10 yuan.
Finally, the specific price also needs to consider the relationship between market supply and demand, the bidder's bid and other factors. Therefore, in order to accurately evaluate the value of this ancient Jiaqing Bao Tong coin, more factors need to be considered. It is recommended to consult a professional coin collector or antique dealer to get a more accurate evaluation.
