 The mint is considering expanding the use of multi-ply plated steel technology to other coin denominations due to volatile base metal prices and rising production costs.On February 3, 2009, the Royal Thai Mint released the new series two-baht coin, minted in 2008, which uses aluminium bronze in place of the former nickel-clad low-carbon steel.The original two-baht coin was minted 2005-2007, and was the sole two-baht coin in circulation from 2005 until February 3, 2009, when the new design was released.
