In any workflow or SMS templated message, put {{opportunity.lead_value}} and notice that it renders as plain text (if you enter "3000" in the Opportunity, it'll output as "3000")
Since Opportunity Lead Value is a monetary value, it should output as such, just like a custom monetary field would output as currency: $3,000.00
I understand a workflow could use Number Formatter, but SMS/Email Templates cannot.
And simply adding a dollar sign in front in the SMS Template would output as $3000 without commas or decimals - inconsistent from a monetary custom field on Opportunities.
