OK, sorry for the delay. Your coins are:
#1: Xiang Fu yuan bao, fourth reign-name of emperor Zhen Zong, used AD 1008-1017.
#2: Sheng Song yuan bao, "running script" variety. "Sheng Song" was a substitute reign-title for the "Jian Zhong Jing Guo" era of emperor Hui Zong, corresponding to AD 1101-1102. Hui Zong fancied himself an artist and calligrapher; his coins show a bewildering array of varieties and styles, of which "running script" is one of the more common, though harder to read.
#3: Shao Sheng yuan bao, "running script" variety. Second reign-name of emperor Zhe Zong, used AD 1094-1098.
#4: Jing You yuan bao, "regular script" variety. Third reign-name of emperor Ren Zong, used AD 1034-1038.
All of these coins are fairly cheap and common, worth only a few dollars when fully identified. The reason that these thousand-year-old Chinese coins are so cheap comes down to sheer numbers made. Mintage records for some years of the Song Dynasty survive, and record three million strings of coins cast each year. A "string" is 1000 coins, so that's 3 billion coins. Per year. So even the relatively brief eras, such as Sheng Song, have many survivors down to the present day.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
