The movie Sinners has two post-credits scenes.

• The first post-credits scene is an epilogue set 60 years after the main events of the film, in 1992. It shows Sammie, now an elderly blues musician played by Buddy Guy, performing at his own club named Pearline's. Stack and Mary, now vampires, visit Sammie, and Stack offers to turn Sammie into a vampire, but Sammie declines

• The second post-credits scene is less plot-heavy but serves as a capstone to the story, allowing the audience to spend a little more time with the characters and the world of the film

So, there are two post-credits scenes in total after Sinners ends
