I am still learning to properly identify cleaned coins. Are the heavy lines seen on the face of this 1889 P normal circulation wear or is this mechanical cleaning damage?

    Yes - guilty until proven innocent.

    Welcome to the forum! :)

    Photos are needed for the best responses. You may need to wait until you are an approved member to post photos.

    Very good chance it could be cleaned but with Morgan dollars there are quite a few with die polish lines that can look like it has been cleaned. No way to tell more without photos.

  • Thank you, I used the photo bucket url link but must have done it wrong. I will try again.

    First a video from PCGS to lay a foundation:


    Another video that shows examples beginning at around 3 minutes:


    Hope this helps!

    Also, are the lines on the on the coin indented into the metal? Use a loupe to determine. Parallel scratches may indicate a wipe that indicates a cleaning.

  • The image should now be loading with the original post. to me they look indented and uniform like a wire brush was used.

    Yes, I’d say those lines are reflective of a wipe from a cloth or paper something similar.
