I have a clear glass gallon jar of Wheats and keep culls separate. I am getting tired of new culls forming after I separate the bad ones out, then having to go back in and take out the new culls. Does anyone have any advice? They are in a closet and the room is 84 degrees. I am certain the climate is impacting that.

There's tons of info on this forum. I've been using ziploc bags, snap top food containers and desiccant packs recently.
Then plastic tubes and 2x2s for better and best ones.

After doing additional research, I should streamline my question. How can I keep the patina from growing on these coins. Maybe 5-6 months ago, I separated the bad ones from a gallon jar and suddenly awful green growth is popping up on a handful of them.

Without getting into the definitions of "cull" and "patina" or to which group of coins "these" and "them" refer, my suggestions:
a) Thoroughly rinse all present coins in distilled water and (allow to) completely dry before re-jarring.. Do the same to all 'new' coins prior to adding..
b) Almost everyone "forgets" that even in these early days of our current still-kinda-new-at-built-in-obsolescence disposable plastic worldview the lids on most gallon-size jars continue to be made from some kind of metal.. Many now have a sort of liner on their underside.. Many yet do not.. It's this latter group that can be problematic, as they (can) add to the reactions already taking place from interactions among the various substances adhering to the coin's surfaces along with the coins themselves, which can be aided by pollutants & humidity in the air trapped in the jar as well as also reacting with the lid's metal..
Some type of seal needs placed between the lid and jar's innards as close as possible to the lid's inner surface.. I can't recommend spray plastics / paints / clearcoats since they all have their own off-gassing situations.. Even stretch-y wraps can be problematic.. What I've found to work best is either wax paper or Ph-neutral paper.. Better yet: a combination of the two.. Simply lay them across the top and replace lid; no need trying to size for the inside..
c) Should you want to go full-bore by adding vacuum to the jar, here's a cheap and easy way to do it: Drill a hole in the lid that will fairly snugly accept a length of 3/8 to 1/2 inch inner dimension tubing, completely sealing at external lid juncture with something non-toxic.. Whenever you want vacuum within simply draw through the tubing and clamp off..
No more grow-y stuff in your jars..

84° will usually mean realitive humidity above 60% (unless desert climate). Green "stuff" as you call it is verdigris, it is a copper coin's viral pneumonia, it WILL pass from one coin to another. The old adage of one bad apple spoils the bushel applies here. Like pneumonia, you have to "heal" it, remove what is causing it to breed. That is the verdigris AND humidity(moist air). Learn what Verdigris really is and looks like( not all is green). I would first off dump acetone in your jar, swirl the coins around, leave overnight, covered. Then rinse w/ distilled(not "purified")water and air dry. Then separate. Store in Airtight container w/dessicant packs.

Would I be better off using plastic containers with plastic lids as opposed to the glass jars with the metal lids? Would acetone fall under the technical definition of cleaning coins to improve their shine, even though that is not my goal here.

It's primararily PVCs in plastics that are coin's nemesis.. I wouldn't "think" anyone today is still making (food) containers out of PVC, but hey -- it's 2018, so if it's fradulent and can make a buck it's probably out there somewhere.. But I digress.. There's sooo much more involved than at first blush.. Read this heah article --> https://www.usgoldexpert.com/articl...-are-ruined/ Almost twenty-five years old n still spot on.. Quote:

Acetone's most prominent use is for removing plastic stuck on coins that's left behind upon transference out of the early-days pre non-PVC flips, followed by tape residue removal and lastly some types of dirts.. Acetone doesn't shine coins per se but may make some look like that thanks to removal of certain baddies, including some verdigras.. While acetone is about 100% inert on many pure metals to include gold and silver it can also mess with patina on copper -- which covers many coins including most gold and silver.. Sooo... Again, check out above article -- and this one as well: http://www.coinmine.com/WhatYouShou...Cleaning.htm I apologize in advance to the mods if I shouldn't have posted these links -- they are to information and have nothing to do with whatever site to which it may be posted..

The plasticizers make PVC soft and pliable. They also leech about and break PVC down into the stuff that attacks our coins. PVC is naturally rigid and rather harmless. Just look at your home plumbing, if not copper it is PVC. You drink that water, right?  |
