Most of CKN Kring PraDhanporn B.E.2512 are Thai-digit-9 mold. Normally, it's hard to find a Kring of this kind, but much harder is the plain-back mold as seen above. 

The content of the Kring is really good because it's mixedly melt with the leftover bronze that cast the main major Buddha image "Phra Buddha Mongkol Nayok" of Wat Wangkrachom in B.E. 2508. 

CKN is highly respected as a greatest Guru of this modern age. He ordained for 46 years since B.E.2468 and was an ultra-high Dhamma practice monk. He was a strict vegetarian and took only one meal a day, and never stepped out the temple but simulated his Kuti (monk house) as a quiet jungle for practicing until reaching ultra-high Dhamma.

As recorded by advanced Dhamma monks, CKN possess special knowledge on precognition and mind detection. He could detect people mind and knew his own passing date in advance.

One day before his passing, he told his nephew not to deliver him a pack of cereal food anymore and also hinted his close neighboring monk that the day he was not present at the Bosth for chanting would mean the day of his death.

CKN passed away in early B.E.2514 at the age of 75, with his hands joined together paying the last respect to Lord Buddha. As told by high rank monks, his cremated relics later became crystal-like materials or Phra Dhat which hints us his highest Dhamma attainment.  

Due to his absolute cleanness and his ultra Dhamma attainment, all amulets blessed by him are so efficacious in Metta, wealth & fortune, and life protection.
