I am using a!currency to show thousand separator

Instead of $ would the code 'USD" work? like this

a!currency(
  isoCode: "USD",
  value: 1234.56,
  showSeparators: false,
  format: "CODE",
  indicatorAlignment: "START"
)

Using 'format' parameter you can show either $ or USD. 

thanks for the reply...actually the display columns are number of packs so no need to have any currency symbol.
