Because you need a subset of data you need to build a list of currency symbols and sort that.

Dim currencyList As List(Of String) = New List(Of String)

For Each cultureInfo As CultureInfo In CultureInfo.GetCultures(CultureTypes.SpecificCultures)
    Dim regionInfo As RegionInfo = New RegionInfo(cultureInfo.LCID)
    If Not currencyList.Contains(regionInfo.ISOCurrencySymbol) Then
        currencyList.Add(regionInfo.ISOCurrencySymbol)
    End If        
Next

DropDownList1.DataSource = currencyList.OrderBy(Function(k) k)
DropDownList1.DataBind
