Austria Philatelic Cover Lot 1976-2006: Registered Mail, Souvenir Sheets, Commemoratives & Definitives

Here is an analysis and market price evaluation for each of the postal covers shown in your images.
As these covers primarily feature common modern and definitive stamps of Austria (Republik Österreich) issued between the late 1970s and the 2000s, their value lies mainly in their postal history usage (such as registered mail tags, special cancellations, or commemorative event covers) rather than the individual stamps themselves.
