In the early days of Song Shenzong's rule, Wang Anshi's new law was promulgated, and this coin was minted to stabilize economic turmoil. Its appearance slightly changed the economic development of the Song Dynasty, and its output was large, it was urgent to issue, and its production process was simple and fast.
Yuanfeng's Bao Tong edition is very complicated, among which it is rare to recite small flat coins, small flat characters, official scripts and iron coins, and even rare to recite "Shaanxi". To appreciate Yuanfeng Bao Tong, it is necessary to read this book first. The style of official script is Yuanfeng Bao Tong, with harmonious layout, dignified implication, uneven strokes and distinctive features.
Secondly, it depends on the casting stage of coins. Coins are very regular, with moderate thickness, clear outline and natural degree. This Yuanfeng Bao Tong is a treasure.
Finally, look at the rust phase, thin rust, patina and moisture of Yuanfeng Bao Tong, and it can basically be determined that it is an official kiln product.
I would like to remind you that the most important thing in collecting ancient coins is the appearance, that is, the clarity and preservation of fonts and the rarity of products. Most kinds of Yuanfeng Bao Tong are very cheap, and most coin collectors have seen them, so the collection value is very small.
