However, please note that we do charge a nominal fee to cover the cost of processing the coins. This is generally cheaper than bank charges. For every 1000 pieces of coins (regardless of denomination), the charges are at S$3.70 and the balance coins are pro-rated accordingly (i.e. 300 pieces /1000 pieces X 3.70 = S$1.11). All prices stated includes GST charges.
