Well, after nearly three months of forgetting about them, I decided to do an update. The copper and the undamaged Zincoln are not very damaged (except for some minor discoloration), but the damaged Zincoln sure looks ugly.

I had forgotten this as well.

Thank you for the update. The damaged Zincoln is looking rough.

It sure is. It had a lot of dirt caked to it, so it required quite a bit of picking with a toothpick.

After 3 months buried, I dug up the coins today. Pictures later tonight, I will say that neither type fared well.

Here's my update after 3 months.

I never made it around to burying one set in dirt so I have 3 set on concrete and 3 set on wood.

I went out to get them and one of the wood ones is missing

OK, as promised, here are the coins. A lot of corrosion on the copper cents, verdigris I believe. The zincolns have been bubbling out zinc through any opening in the copper skin. The date on the 2014 is nearly illegible.

Well, it's very apparent why they still make billions every year; The old zincolns are evaporating and the coppers are being pulled by hoarders. Pennies are toxic little slugs designed principally to impede cash transactions and to keep zinc mines open.

Every time one is used or produced we're all a little poorer.

I have dug up some truly horrible zinc cents while metal detecting. I live in SE Wisconsin and copper cents come out of the ground in great shape. Zincs corrode. I've thrown out a bunch of them because there was nothing left but a semi-round piece of corrosion.

Interesting thread. We often do those pressed pennies at various places. We are sure to bring copper pennies since the zinc coins do not look very nice once pressed. I do recall one of the machines, I think in Gettysburg, saying to use pennies prior 1982. Yes, true how the zinc are really not quite as sturdy as the 95% copper. They are found often, but the copper ones are kept!
