Very little. These replicas have a layer of gold on the foil that is an atom or two thick. It is not really measurable and it would take thousands of them to make an amount worth anything. You might be able to get a $1 or two.
The gold replica stamps have a minimal value. The amount of gold is very small and not worth more than a few cents.
