Products with an A-rating are among the most commonly traded and liquid options available. These coins and bars offer a strong balance between a competitive price per gram and a low spread, making them well-suited for investors who want to acquire physical gold or silver efficiently. Due to their global recognition, they are typically easy to buy and sell.

Products with a C-rating are primarily valued for their collectible characteristics. This may include limited editions, unique designs, or historical significance. As a result, their price is often less closely tied to the underlying metal value. These products are typically chosen by collectors rather than investors focused on efficiency.
