I have about $15 (face value) worth of IHP and Wheat culls I'm seriously considering burying in my back yard in a coffee can or something. They came as part of a lot of "culls" I bought online that, in my estimation, shouldnt have been called culls, but "totally trash copper." Any suggestions about what I can coat and package the coins in to reduce corrosion while they sit in the ground until space aliens or my great-great grandchildren discover them?
Seriously....someone's gotta do it, right? Time capsules for 2040.

Jim, why not seal them in plastic? That should keep the oxygen out, and "protect " them until so,meone dige them up, looking for fishing worms!

If I were doing that I would probably add mineral oil to the plastic on the inside layer just enough to fill in the gaps. This would keep them safe, but not too much oil that would make the bag break. I would place larger and larger bags on the out side edge. Mineral oil to preserve the coins. Two layers to keep the free from corrosion. Yep, that how I would do it. Maybe some kind of coffin to keep the moisture out. Plastic coffee can or even a mineral oil bottle. Dimes and Cents would fit into them. But I would take BU coins and save them. That way the finder would get something that would be real valuable when they find it, instead of a container of damaged coins. IMHO

I did it back in 1982. As I remember, a roll of circulating cents, a roll of silver dimes, a current newspaper, a new pack of baseball cards, and a note telling about me. Buried in North Memphis in the woods behind the house I lived in.
It was sealed in a quart size ziploc that was in a gallon size ziploc, inside a coffee can with a plastic lid.
Wow...that was over a quarter century ago.

if you really want it to last, do the ziploc thing and then bury it all in an airtight plastic container that is along the lines of tupperware. The thin plastic cracks and leaks over time:-)

I'll put in my .02 from managing outdoors gps/geocaching stations--ziplocs and tupperwear fail within a year outdoors.
So here's a bit of unconventional advice: find some way to remove all the moisture, seal and sink the coins in a block of pure beeswax. I know it sounds a bit offbeat, but I do know from numerous marine excursions that beeswax seals out water, salt and corrosion for centuries. It often washes ashore from Spanish shipwrecks after centuries of exposure, and when cut open is still fresh and obviously intact from the elements.

Thanks, you all...i like the beeswax idea and the mineral oil idea (the latter probably dissolves pvc, no?).

I like the old standby...a glass jar like peanut butter use to come in (with a good rubber seal). You could also add mineral or or seal the lid with beeswax or do both.

I would start with a vacuum sealer.

If they aren't good enough for you, what makes you think anybody in the future wants them LOL. Why not just put them back into circulation where a young collector might be thrilled to get one in change.

Bill, yeah--that wouldn't be good in bear country either! Well, it was just an idea, lol.

Vacuum seal them in some good non pvc vacuum bags then put them in a glass jar with a good sealing lid and then encase the jar in lucite. Nothing will effect them in that stuff. And will make the finders have to work a little to get their prize..lol
Also add a few older MS coins, maybe a couple silver dimes and wheat cents, so that they are not getting just junk.
