In B.E.2506, a batch of round shaped medals were created for Luang Phor Ngern. There are basically 3 sizes created, namely Phim Yai (large size), Phim Klang (medium size) and Phim Lek (small size). The large size piece is very commonly referred to as Rian “Jikko” Yai (gangster) due to its large size, which is a stereotype of gangsters who wear big amulets on their necks. The medium size piece is referred to as Rian “Jikko” Lek as it is similar in appearance to the large size pieces, only different in size. The small size piece is referred to simply as Rian Klom Lek (small round style) and is different in design and hence named differently.
Rian Jikko Lek was created using 2 different moulds, which results in 2 slightly different features. The popular mould or Phim Niyom is known as Block Asana Loy, which means the seat which Luang Phor Ngern is sitting on is “floating”, not touching the rim of the medal. The ordinary mould or Phim Tammada is known as Phim Asana Tit, which means the sides of the seat is touching the rim of the medal.
This batch of Rian Jikko medals has been very popular even from the time they were distributed as there were many positive experiences and miracles recounted by devotees. Due to its popularity of this batch of Rian Jikko, there have been many imitations, whether low quality or high quality, over the years. Some pieces even have different features which can be differentiated outright.
