  • Cast Bars: Think of these as the classic gold bar. Made by pouring liquid gold into molds, they have a bit of a rough look with some cool imprints from the mold. It’s their rugged appearance that many find genuinely authentic.
  • Minted Bars: These are the sleek, modern cousins of cast bars. They start as gold sheets and are precisely cut into bars, often showcasing detailed designs. The result? A polished and refined bar that both investors and collectors love.
  • Commemorative Bars: Special occasions call for these special bars. They’re minted in limited numbers to celebrate big events or achievements. While their gold gives them value, it’s the story they tell that really makes them stand out.

Each type of gold bar has its unique charm, fitting different tastes and investment strategies.
