Proof v. Non-Proof?

[apush]

How can you tell a proof coin from a non-proof coin? For example, a 1990, Proof, No S cent, from a standard 1990 cent with no mintmark? By weight? color?
I know we all get 1990 cent coins, but I would strangle myself if I chunked one into the dump pile.

Thanks for any responses.

Typically by the Frosted Details, and Mirror finish in the fields....

But I was wondering if 1964 half dollars the same...do they also have the same frosted details and mirror finish fields as modern coins?

Yes, the answer is the frosting. The mirrorlike finish could look similar to a very sharp non proof coin, but the frosting gives it away. It is easy to spot when you know what you are looking for.

Take a look at some proof coins for sale. See how the frosting looks, and you'll see the difference. :-)

No worries. In your example, all 1990 cent proofs will have an S mintmark. In fact all modern proofs will have a S mintmark (except for West Point). Modern proofs will have a mirror-like field with frosty devices. Now the question arises for how to discern early proofs as they were minted at Philly? This becomes more difficult as the coin circulates. Some proofs were created with deep cameos, but more likely the proof will have no distinguishing surfaces from the field and device. You will be able to tell by the strike. It will be sharper, and more detailed than a business strike. Also, the entire surface of the coin will have a sheen of luster. These early proofs found in the wild are tough to discern as the abrasive nature of being in circulation will diminish the features. Once you found one of the early proofs, you will know.
