These coins were all produced abroad, and they feature changes in year formatting and design differences over time. The coins were initially produced with the R.S. year system but transitioned to using the B.E. system from 1913 onwards.<ref>เหรียญนิกเกิล ทองแดง ตราอุณาโลม - พระแสงจักร | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department.

‌</ref> The 1 Baht

coins were replaced with banknotes starting in 1918 due to the high cost of silver. The 2 Salung and 1 Salung coins experienced changes in metal composition due to fluctuating silver prices during World War I, and these coins have slight design variations based on these changes.

During issue, there were also various debasements of the silver content of these coins. Initially, the composition was 80% silver and 20% copper. In 1918, during World War I, silver prices surged, leading to a change in the composition to 65% silver and 35% copper. In 1919, the silver percentage dropped further to 50% silver and 50% copper. After the war, in 1919, the composition returned to 65% silver and 35% copper.<ref>เหรียญเงิน พระบรมรูป - ตราไอราพต | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024.

‌</ref> In 1917, the price of silver rose and exceeded the face value of silver coins. The coins were then melted down and sold. The government solved this by changing the pure silver coin to alloy. Vajiravudh eventually forbade exports of Siamese coins. In 1918, the usage of 1-baht coins was nullified and 1-baht banknotes were introduced. Coins were recalled and kept as a national reserve.

Near the end of this issue of coins, the transition into decimal currency was completed. The Rama VII coin was produced in two denominations, 50 Satang and 25 Satang, and marked the transition from the old currency system of "สองสลึง" (two salung) and "หนึ่งสลึง" (one salung) to the new system using Satang as a unit of currency.<ref>เหรียญเงิน พระบรมรูป - ตราช้างทรงเครื่อง | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department.

‌</ref> Though, people today still refer to these denomination using the old terminology.
