Care of Your Bullion Products - What are milk spots?
Milk spots are very common on silver coins and bars; it happens when condensation reaches the silver. Depending on your luck, sometimes the whole bar or box comes out perfect. We take every precaution to ensure our bullion is shielded from the elements. We do not open mint sealed tubes when shipped whole. That spots sometimes appear on mint sealed items that we ship out is indicative of their natural occurrence and difficult prevention.
