What is the Difference Between Type 1 and Type 2 Silver Eagles?

By GovMint :

American Silver Eagles are a popular choice among collectors, and they come in two distinct types: Type 1 and Type 2. Type 1 Silver Eagles, minted from 1986 to mid-2021, feature the classic Heraldic Eagle reverse design by John Mercanti, a prolific coin designer and former Chief Engraver of the United States Mint. In mid-2021, the United States Mint introduced the Type 2 Silver Eagle, marking a significant update with a new reverse design by Emily Damstra. The Type 2 reverse design features a more naturalistic depiction of an eagle coming in for a landing, grasping an oak branch.

In addition to the reverse design change, Type 2 Silver Eagles also incorporate an enhanced security feature to prevent counterfeiting in the form of a reeded edge variation.
