1963 Thailand Royal Thai Mint Commemorative Coin Set of 30 Coins With Orig Box

Description

Commemorative coin set issued in honor of H.M. The King Bhumibol Adulyadej P.R.'s 36th birthday on 5 December 1963.
In original case, probably unopened for 50+ years.  The box was stored in a container with mothballs, so it does smell of mothballs.
There is some discoloration at the edge of the large coins.
Original issuance paperwork is included.  See photos.  Feel free to ask questions.  This was in a relative's estate, and I really don't know much about coins, so I'll do my best to answer.
