Good Afternoon Kim,
The national currency for St. Lucia is the Eastern Caribbean Dollar (XCD; symbol EC$) = 100 cents. Notes are in denominations of EC$100, 50, 20, 10 and 5. Coins are in denominations of EC$1, and 50, 25, 10, 5, 2 and 1 cents. US Dollars are also accepted as legal tender.
The Eastern Caribbean Dollar is tied to the US Dollar at EC$2.7 to US$1.
Please note: - US Dollar Travellers cheques are becoming extremely difficult to exchange so we recommend you take US Dollar cash. Places that do exchange traveller’s cheques may charge a 10% handling fee.
I hope this helps.
Kind Regards,
Mildred.
