I have 1979 D & P mint sets that I want to open , scrutinize, and transfer to individual holders for possible grading by third party (NGC). What are the procedures I should follow. Will acetone cleaning before transfer be detrimental? And what is the best way to store after transfer in anticipation of sending for grading. After 41 yrs in the cellophane they look like they could use a little sprucing up. Your suggestions would help a lot.

Don't clean them. Going to need high grades to justify a TPG,look here http://numismedia.com/fmv/fmv.shtmlA coin need a retail value after slabbing of $150 to justify all costs involved in sending to a TPG. John1  |

Just a quick anecdote about acetone. Watch out. Acetone melts certain plastics. I once ruined a coin by melting/fusing it to some plastic. I was unable to remove it. Luckily it was not a valuable coin.

As you may already know, just because coins in mint sets are uncirculated, it does not mean they are of any higher grade than what you might find in unc bank wrapped rolls. The coins in mint sets are simply packaged this way for sale to collectors who want mint sets of all the coins for that year. You can get some nicer examples from sets that may have suffered a bit less contact marks having not traveled around in bins and mint sewn bags but this does not make them exempt from having issues. One thing I remember from the 70's though, it seemed it was easier looking for better struck coins. For example, I cherry picked some better Jefferson nickels with decent step counts that I normally didn't find from rolls or at coin show bourse tables. |

From the previous three posts I get the idea that the coins would be better off remaining in the Mint sealed packs.

Your sets are not valuable enough to spend money on for grading.

For the fun of it, please post a few photos of the coins in question. Thanks.

The sets are still intact. I have spent some time looking more closely at them. The nickels and dimes in both sets are definitely out of the equation. Both SBA's are narrow rim. Only the quarters and half dollars show any promise. Maybe the cents. I am new to this game and quite surprised to find out that mints sets do not contain quality coins. One of the nickels has no steps and neither dime has bands. I will send some photos of the better ones if it seems they may be worth the expense. Not looking that way so far. Thanks for the input out there! |

Bluefalco, glad you read the feedback and took a closer look at the coins in your sets.
I'm glad you understand now what you will generally encounter in mint sets.

1. Grading coins from Mint sets?- perhaps no.
2. Grading specimen coins (not proofs) of the same date? perhaps.
Still a matter of judgement to submit for the second alternative.

When grading, its always worth to look at the coins sending in to make sure they are worth it. I'm a fan of the 2009 Lincoln Commemorative cents, I picked up a few sets and picked the best of the series to get graded. Ended up getting 3 top of the pops. Just take your time, look at each in detail and if its worth grading doing it, if its not don't.

OK, I'm a little confused. Bluefalco mentioned giving these coins an acetone dip to clean them, and John1 said don't clean them—sounded like it might affect the grade. I thought Acetone didn't hurt coins. (While I'm asking about acetone, I've asked a couple times on other topics whether dipping a proof in acetone did any harm and never saw an answer—maybe I missed it. But does it?)

Unless you know what you're doing and doing it yourself, I would be apprehensive suggesting any type of cleaning to someone else. Especially since you don't know them or know what they are capable of. I doesn't take much to screw-up or destroy a coin! |
