Most coins in my yard corroded

I am just learning the basics here and doing a little practicing here in my yard. I have found quite a few coins, but most are eaten up. I'm wondering if a previous owner used to dump chemicals like gas/oil for example before everyone became knowledgeable of the harm from dumping stuff in their yards? It's not an old place(1976 or so) but is kind of depressing to see so many coins ruined. I have found quite a few tire stems so maybe one resident used to do some auto work in the yard and I can see that's just chemicals everywhere.

fertilizer does that to modern coins...especially zinc pennys.you dont mention the type of coins but I bet the pennys suffer the worst.If you have evergreens...they produce pine needles etc which are very acidic.If he was dumping motor oil or the like your coins would be as fresh as spring air.

The coins that are all eaten up, are they pennies? Pennies from 1983 thru today are primarily zink. Can you post some pics to illustrate your point?

Gasoline won't hurt a coin and oil will actually preserve it better. It's the phosphates, sulphur and nitrogen (added or natural) that attack coins. Worst are the modern clad because they are self-contained galvanic corrosion generators.

I believe that peeing in the yard is not good for coins

bigfoot 1, If you had given all your finds to your ex, she may still be your wife. Think about it, and get back to us.

Dewed: Same here. The zinc pennies in my yard look moth-eaten while the coppers are oxidized but mostly intact.

Sorry, been away, I'll show some pics but do think they are the zinc pennies, there are a few I can't recognize. Thank you all for responses!

Okie, finally got the pics. Seems like the nickels and dimes just start to rust and wear out by the letters first,

The blob I didn't mean to have in pic, is just a lump of lead I think

Thanks for the pic, the pennies are all 1983 or newer I bet. These are the zinc we mentioned that they corrode badly. The others are simply clad that had discolored due to the iron and other minerals in the ground. When you dig a true silver coin, it will come out of the ground as pretty as the day it was dropped. Nothing to worry about, normal condition for coins being in the ground for quite some time.
