Question: What is the difference between a "Poured" bar and a "Struck" bar?

Question: Who was Engelhard?
Answer: Founded in New Jersey, Engelhard Corporation was once the world's largest refiner of precious metals. Their reputation for purity and integrity remains the "gold standard" (or silver standard) in the industry today.
