The First Medals ( Rian / Rien ) ( Roon Raek ) of Wat Chang Hai
the first medals were designed and created by Archan Tim in 2500 B.E , there was 3,000 of them, made of copper. This batch of luang phor thuad had big head , so they call it as “big head” medal.
After they were distributed up , Archan Tim created more around 5000pcs in 2501 B.E by using the original moulds but different materials , silver plated medals and gold plated medals.
Nowadays the roon raek rian are rather expensive. The silver plated and gold plated rian are higher price compare the copper ones. In my opinion , copper medals should be more expensive as it was created 1st. however , it is good and worth both ot it.
