If You Were A Coin Grader, What Would You Grade...

If they're in cellophane, I would assume that means that they are relatively old? Not sure when they started with the hard plastic for the proofs. Regardless, you can always post pics here and let the folks give a shot at grading. I really don't see many proofs posted here in the grading section, so why not give it a shot.

As for the potential grade, I think it may depend on the age? If I understand correctly, the mint has been getting better and better at their quality control, so newer sets will probably yield a minimum PF67 grade, but I don't honestly know about the older sets. I'm sure some long time collectors may be able to help you better than I.

What were the dates you were considering to get slabbed, and pics would help.

I have seen these lots on ebay. Is that where you purchased these? If so, you can be pretty sure that these coins have been picked over for any that would be worth sending in. I hope that I'm wrong, but don't be surprised.

Please post a list of the coins that you think might be worth grading.

I think the last year of the flat pack proof sets was 1964, as the special mint sets came out in hard plastic.

Hi Landslide, just stopping in again to give you some more info. I checked the ebay number you provided. This seller is listing mint sets, not proof sets. You can look on the left side of the forum in the "glossary" here to learn the difference, as it would take a little bit to write up. Bottom line, proof coins are struck from specially prepared/polished dies along with other variations such as striking pressure etc, and usually result in a much more detailed strike.

That being said, these are "mint" sets which are uncirculated coins. These are not struck on the same dies that the proofs are struck. While you can probably get some decent coins in decent mint state levels, as was mentioned earlier, the added value coins such as "full bell lines" and Full steps" coins will be hard to find in lots like this.
