In B.E.2509, Wat BangKhunProm held a major celebration to build a large statue of Buddha and Pra Somdej Archan (Toh Promarangsee). During that time,  there was also a batch of somdej amulets being chanted. These Somdej amulets are mixed with many different types of amulets from old chedi all over thailand; old somdej amulets from Chedi of Wat BangKhunProm(The old Somdej that were placed there by Pra Somdej Archan Toh, a hundred of years ago), amulets from Chedi of Wat Sam Pheaum, amulets from Chedi of Wat Kroosalort, Ayutayah, Pra Nang Phayah amulets from Chedi of Pitsanulohk and even first batch of Wat Paknam amulets.

This batch of amulets was chanted at Wat BangKhunProm. There were many famous monks participated in the chanting:

1. Luang Poo Nahk, Wat Rakang
2. Luang Por Ngern, Wat DornYaaiHorm
3. Luang Por Tae, Wat SahmNgahn
4. Luang Por Nor, Wat GlahngTahReau
5. Pra Archan Tim, Wat ChiangHai
6. Pra Arhcan AmPon, Wat Prasat
7. Pra Archan Dteum, Wat PraLory
8. Luang Por Horm, Wat ChakHaMahk
9. Tan Jow Koon WimLaGitJahn, Wat ChaNaSongRahm
10. Pra Kru PlayWiSutTiWat, Wat Suttat

One important thing to note about this batch of somdej amulets, is that every pieces of amulets are different and not the same in terms of clarity and sizes, this is because this batch of amulets were hand made. Due to the mixtures of many types of powders, the colour of the amulets also varies from one another, some are more white, so more yellowish and some even can see old somdej powder. In regards, to the temple chop at the back of the amulet, some amulets has a clearer chop, some lighter, some darker and some without chop.

Pra Somdej Bahng Khun Prom Roon 09 is as good as the old somdej BangKhunProm chanted by Pra Somdej Arhcan Toh, this is because it contained the old somdej powder. Not only this, it was also chanted by many famous and good monks, it was chanted for a good purpose as well.
