Was it tarnished very bad?
Silver does not tarnish in the ground, as long as it is not exposed to oxygen there.
As long as it remains burried, it will remain clean, hense those silver coins that are dug here in the US
every day that look like they were dropped yesterday.... even though they were lost 1-2-3 hundred years ago.

It would be Rare for a Roman coin which is normally found in ploughed fields not to be exposed to Oxygen. However the ploughing effect does keep them clean sometimes depending on the purity of the silver, ground conditions etc....
Tin foil & abit of spit and you get the same resultbubbas said:tarnishing on silver coins is normal (because of the cows droppings).
the deeper the coin has been under the ground the better the quality is.
when the coin is exposed to air ,then the tarnishing begins.
most silver coins i find are very black ,bud i know how to clean them (with a citron liquid).
thats why i like to find gold (thats always in perfect condition haha).
gr bubbas (sorry for my englisch)
Coins exposed to sunlight will turn black, also stubble burning (before it was banned) would account for black Silver Coins.TORRERO said:dugfinds said:TORRERO said:TXTim said:That is some old old old silver!

Well I'm not sure if that is true either, your assuming that plowing the field places a silver coin on top of the dirt, and that
all silver coins would at some point be clear of soil to the extent to cause tarnishing on silver, but in fact when I lived in Spain, and dug many silver and Roman silver coins, none of them ever came out of the ground really "tarnished"
Sometimes silver will be "stained" so to speak, and I believe this is caused by olterior factors such as Iron, or acidic soil
close to the coin. (such as fertalizer) But tarnish makes silver look dull and dark colored, sometimes even black, such as
your granny's silver service set that was left on the shelf for years and years...
Coins, much older than even Granny, come out of all types of ground and soil, even plowed fields, with hardly any tarnish at all, even after several thousands of years...
Also another thought, when a coin is dropped on the ground, it does not immediatly become burried, but remains on the surface for sometimes as long as 6 months to a year, before being covered by the ground, and yet silver that started that
way (all coins where lost by dropping) turn up without any indication of tarnishing... maybe there is a soil factor that takes
the tarnish off while a coin is in the ground.. ?
so what's the explanation ?
