1962 Thailand 5 Baht

This 1962 5 Baht coin was struck as a silver proof to commemorate the 25th anniversary of King Bhumibol Adulyadej's ascension, a milestone that underscored Thailand's royal continuity amid post-war changes.

Weighing 15 grams and composed of 90% silver, it features the king's portrait on the obverse and the Thai royal arms on the reverse, with a reeded edge for added security. The proof finish gives it a mirror-like surface, though exact production techniques from the Bangkok mint remain murky—records from that era are sparse.

As for rarity, I've handled a few over the years, but mintage figures? Lost to time, likely in some bureaucratic shuffle. Some collectors chase these for the silver alone.

Oh, and if you think every anniversary coin is rare, wait until you see the common ones cluttering my desk.
