Is there any way to tell a circulated proof from a business strike?

We know that proofs have sharper detail and a different finish, but what happens when one slips into circulation and diplays Fine-12 details?
Can the grading services tell if it's a circulated proof or a typically worn business strike?

    Referring only to Philadelphia issues
  • For later proofs:
    S San Francisco
    W West Point

    Probably no way to tell for earlier Philadelphia proofs. Especially in that grade.

    Unless it's an error that only occured in the proof coins. 1960 DDO Roosevelt Dime is an example.

    If the coin is an AU or a choice EF, many of the Proof characteristics are still visible. Much of the luster and additional sharpness will still be evident. Once the grade falls to VF, the task gets harder. One might note a wider rim, and some Proof coins were made from dies that have markings that will show their original origins. Still, most of the time a considerably circulated Proof will be identifiable only if the coin is question is a Proof-only issue.
