1970-s small date

[Guest]

as most are aware, i have a 72 ddo with a green spot, old news. looking this afternoon, i find one of my 70-s ms 66 pcgs has caught 4 spots on the obverse and a whopper on the reverse. a beautiful shade of green, but from where. come on guys help, i dont want to lose my entire collection of slabs cause i'm doing something wrong

I would be using some Verdi-Care on that myself, but you need to make that decision. One thing for sure, it wouldn't hurt to get some and experiment on some common cents so you can see the results for yourself. My only thought for the rest is that you might store them in an airtight container with plenty of silica packets.

where the.,.,. are store the slabs??? an try mainman750 suggest!

the slabs should be air tight so storage shouldn't be the problem, in any case they are properly stored. this 70-s small date along with the 72 ddo are in pcgs slabs. they are, were stored with 42 other slabbed coins that show no ill effects. i will not point a finger, but only two were pcgs slabbed, no, i didn't say that. if i ever have problems with a coin stored in 2x2s, i will try verdi-care but i won't break open a slab to TRY anything. seems my luck has sucked latley and this is my vent area. so please forgive and ignore.

and oh, by the way wayne, nice pictures

The slabs are not airtight. Buy archival slab boxes and store them in a place with low humidity and low light. As as fixing these - maybe Verdicare with some experimentation or maybe NCS. These are big coins, I would hate to see them made worse in an attempt to make them better.

[Maineman750]

Sorry to say, but I can only see them getting worse if they're left in the slab.

the 72 ddo has been sent to ncs as of this morning. the ms-66 1970-s small date will follow very shortly. i may complain and moan but i will take care of my babies. i did not intend to sound ungrateful or short, but my slabbed coins will only get professional help and that ain't me.

I believe PCGS and NGC altered their guarantee on copper coins as changing condition issues have been plaguing them both. I would call and see if yours have any guarantees on them. Good luck!

NGC did not alter it, however PCGS did. But PCGS still guarantees the coins issued with the original guarantee to the owner at the time of their change (about 18 months ago). So long as you maintain a coin from prior to their change, their original guarantee is still valid.

i hope they fix them, it would be sad if you lose them

[mo052246]

as long as i can get the cancer stopped, they will have done all i can expect. complete conservation would make my year. thanks wolf for the concern

[wolfkill]

[mo052246]

i'm not a winner yet, but i keep trying. with the love and support of my family, how can i lose? i would not have used that analogy had i known. sorry

Hey before you all freak out about copper and humidity and storage, let me remind you that any coin in a slab was previously exposed to all sorts of conditions prior to being put in plastic. Often it is NOT the conditions of where the slabs were stored but rather the slow effects of time to turn the copper, create spots, etc., from when the coin was in contact with contaminants before it was slabed

Now for a story that will freak most of you out but also illustrates my point. The bulk of my collection was purchased and stored while I lived in Puerto Rico. I rented a 5th floor condo and stored my slabs in Eagle brand notebooks in the closet. Routinely I had to wipe the mold and mildew from behind my dresser, bed, etc as the condo faced the ocean and was NOT air-condition. I lived on the flight path of the San Juan airport and the white tile floors , counters, etc had to be wiped down weekly of the spent jet fuel that coated everything and mixed with the dust bunnies and made your feet black when walking barefoot in the condo. When I moved back state side I had to have all my clothes professionally cleaned to get rid of the mildew odor. The eagle notebooks I had to throw away because the three rings in each book had rusted. My point is, not one single cent has had a problem to this day. Not to say you can store your slabs in an aquarium, but common sense is also needed to protect your investments.
