According to the button-book by Alphaeus H. Albert, the US Army Infantry PEWTER 1-piece "eagle-I" button was introduced in 1821. The brass 1-piece version starts showing up in the very-late 1820s.

Actually, both of yours had a letter, because ALL of these US Army eagle-with-shield buttons had a letter on the shield until 1854. From that year until 1902, only Officers' buttons had the letter, and Enlisted-men's buttons had a no-letter shield.
