1957 1 Baht

This 1957 1 Baht coin was the first Thai circulating piece to feature King Bhumibol Adulyadej's portrait, marking a shift from earlier designs that avoided royal imagery for security reasons.

It was struck in copper-nickel, with the obverse showing the king's profile and the reverse depicting the Thai national emblem. The edge is reeded, a standard for the denomination, though some variants show minor die variations that numismatists debate endlessly.

Mintage figures are murky; official records from that era are incomplete, possibly due to administrative changes in the Royal Thai Mint.

Weighing about 7 grams and measuring 25 millimeters across, it's unremarkable in size but holds subtle engraving details that reward a loupe.

As for myths, I've heard tales of hidden inscriptions foretelling the king's reign, but that's just collector fancy. The coin did its job.
