1 oz US American Gold Eagle is issued as $50 USD. TSA says you have to declare anything more than $10,000. $10,000/$50 =200 US American Gold Eagles. Which the street value would be approximately $840,000. So in theory, you can carry up to 200 US Gold Eagles before having to declare. Same thing for other sovereign mints.
