Before talking about the Kangxi Bao Ji Bureau, that is, directly subordinate to the Jizhou Bureau minting, today talking about the Kangxi Bao Xuan Bureau, the Kangxi Bao Xuan Bureau is also directly subordinate, it is called Xuanfu Bureau Minting, Kangxi Bao Xuan Bureau completely shows the close to the central government minted coins are very exquisite this feature, it and the Ji Bureau is very different.
Because I personally think that the casting process of kangxi bao ji bureau is not up to the first-class level, but the xuan bureau is not the same, the xuan bureau can be said to be one of the top two casting levels in the kangxi tongbao, its characteristic is that the word mouth has knife marks, how did this knife mark come from?
Before I also checked a lot of information, there is no clear statement, let's speculate for ourselves, the ancient coins turned into sand and then one by one to add knives, this possibility is unlikely, so the only possibility is in the Kangxi mother money, Kangxi mother money is also the mother money of the Baoxuan Bureau, the traces of the knife may be very deep.
So it turns the sand and casts some knife marks, this should be the most likely situation, Kangxi Xuan Bureau version has some, but very very valuable no, like miniature characters, large characters, Ang Xuan, etc., these prices are slightly floating, did not say that a coin can be worth a lot of money version, which is also a feature of the Kangxi election.
