How do you tell proof and silver proof?

Proof coins are specially minted for collectors, featuring a high-quality finish with a mirror-like surface and intricate details, often struck multiple times for better definition. Silver proof coins are specifically made of silver and also exhibit the same high-quality proof finish. The primary distinction lies in the metal content; silver proof coins contain a certain percentage of silver, typically 90% or 99.9%, while standard proof coins may not contain any silver. To identify them, check for markings indicating silver content, such as "Ag" for silver or specific purity percentages.
