Rare 1990 Thai 10-Baht Coin Fetches 2.54 Million Baht at Auction

According to a report by Khaosod English on August 25, 2026, a rare 1990 Thai 10-baht coin was sold for 2.54 million baht. This transaction took place during the inaugural auction hosted on the Treasury Coin Market, a newly launched electronic platform managed by the Thai Treasury Department.

For residents and collectors in Thailand, this sale highlights the significant value that specific numismatic items can hold, transforming common pocket change into high-value assets. While this coin is an extreme outlier, it serves as a reminder to check older currency for potential rarity. For travellers, this news underscores the importance of the Treasury Department’s modernization efforts, as the new digital platform aims to streamline the trading of collectible coins.

Several details remain to be confirmed, including the specific characteristics that made this particular 1990 coin so valuable compared to others from the same year, and how the Treasury Department plans to regulate future auctions on the platform. As the Treasury Coin Market continues to operate, it remains to be seen how frequently such high-value items will appear and what impact this will have on the broader Thai collectibles market.
