You can set your currency by navigating to /wp-admin/ > MyHome Panel > Settings > Currency.

In this section, you can modify the Currency Name (e.g., GBP), Currency Sign (e.g., £), Sign Position (Before/After the number), and the Format. The easiest way to find your Currency Sign (e.g., £) is by searching for it on Google and copying/pasting it into the MyHome Panel (e.g., search for "Pound Sign").
