Thanks cladking, I wasn't aware of that. I had thought the coins felt a little strange from those earlier sets. Am I right to assume sets after 1984 are OK to keep in the cello? Quote:
The mint set packaging for 1968 to 1984 sets is not stable and has PVC inner lining that touches the coins. Unfortunately the safest bet for long term storage is to remove them immediately and soak them in 91% isopropyl alcohol mixed with a little acetone. Do not use any water. This process will protect any coin not yet showing signs of deterioration and will restore about two out of three of those already affected. |

Some of the individual coins that go into these later sets are not stable because they apparently have some chemical, oil, or soap on them. These will still go bad in time even if the packaging is stable. So far this seems to be worst for the '84-D cent where about 55% of them have problems. I'm not sure that soaking these will forestall the damage. Time don't fly, it bounds and leaps.

I have also found the cello packing from the late 80's through mid 2000's feels more firm and less flimsy than the mint sets of the 70's. I am just not sure about using any chemicals on coins. Something in the back of my mind says don't do it.

My question is what if you break apart the mint sets to have a rare coin certified by one of the grading companies!? For instance I know the 1970 D Kennedy is worth a lot and I only paid 5 bucks for the mint set!? It seems as though the mint sets aren't worth very much

It seems as though the mint sets aren't worth very much The mint sets actually sell at a steep discount to the coins. This is in part because so many coins in mint sets are damaged and because there are lots of culls. Chiefly it's because most buyers of BU rolls want to assemble date/ denomination sets easily and quickly. Someday sets might have a steep premium but by then almost all will be corroded and the market will discount corroded sets. Time don't fly, it bounds and leaps.

I'd do as dealers do and break out all proof and Uncirc sets and put each coin in a 2x2 or smaller flip if for sales.

I never condoned breaking up proof sets . To break a proof coin out and put it in a 2x2 or flip just doesn't seem kosher to me . In the process the coin can get damaged or even a finger print . What I hate most are the dealers who advertise proof rolls in plastic tubes . Come on ! their not proof coins anymore getting hit and bounced around like that . The uncirculated mint set coins are a different story . Most of those coins already have hits and spots in their cellophane holders . No problem cracking them out and holder these coins . Ok, I yes I know you can occasionally find a very high grade coin in a Mint set that you can send in to TPG .  |

Last year I cut open approx 200 mint sets from 1970s, 80s, and 90s. Once you look at each coin under 5x magnification, you'll see most will not grade well as they are dinged up with bag marks and other misc junk. The larger the coin (50c or $1), the more banged up they tend to be. I got lucky on a 1988D LMC that came back MS68. Otherwise most of the other 19 coins I sent in for grading didn't get better than MS65 so I got schooled and technically lost money. However, I consider it as I paid for an education and now have a better sense my ability to grade a coin so I got that going for me, which is nice. Use the search feature of this website. I found many threads on here about cutting open mint and proof sets. Some really nice suggestions. I probably could have spent less than half of what I paid for grading if I went to ebay and bought somebody eles's low graded coins and used them under 5x mag to learn more about what goes into grading. From that, you can make a determination on what you cut out of a mint set is worthy of sending in for grading. When you see MS67 or MS68 coins under 5x, it truly is spectacular GEM quality. |

What do you use for your 5x magnification? I have a magnifying glass but I don't think it is 5X!  |

The magnifying glass I have is 2x with a 5x "closeup" lens in the bottom corner. It is not really good for full coin viewing though, works more like a weak loupe.

I have very few mint/proof sets in original packaging. Except for some of the overpriced sets all others were taken out of the holders, dipped in clean acetone, placed in direct fit airtites and then placed in air tight tubes.

With UK decimal coins I sometimes break up Royal Mint proof or uncirculated sets if certain denominations weren't struck for circulation, as I like to have a full date run in my album. Sometimes it's cheaper to buy up sets from the 1970s and 1980s and break them open rather than pay a dealer several pounds for individual coins that they have removed themselves! |

I sure wish I had done this. It's a crying shame some of the scarce, desirable, and important coins I've lost because I did not. A lot of these sets are extremely unstable. I used to think the most valuable moderns will be ones that didn't appear in mint sets but the fact is lots of these sets will be ruined nearly in their entirety yet their existence stopped many people from setting aside coins in the first place. The early '70's Japanese mint sets, for example, are ruined but few people set aside any coins just because they were available in the sets. US mint sets are often the only source for Gems or even BU's. Where are collectors going to get coins like nice attractive '68 cents now that coins still in the packaging are tarnished and spotted? They'll have to come from the sets of "Complete Memorial cent sets" sold in the back of Coin World for the last 50 years. Twenty years ago they were as cheap as $9.99. The problem is that many of these were assembled from rolls or tarnished mint sets. Only one in a hundred will be nice chBU and most of these sets were poorly preserved. How many collections that cost $10 will be well cared for? How many will survive at all? Time don't fly, it bounds and leaps.
