Sheep Pee And Fertilizer The Reason For Unreadable Discs?

[Spooyt Vane]

On a sheep farm with deep pasture and in the company of four other detectorists ..With over thirty coins (Georgian coppers) found and all thin and unreadable found ..The newbies were asking why and i said preobably sheep pee  On a club site where we took out 300+ copper discs ..Which had artificial fertilizer on it for 30yrs ...It dismays me that should happen to objects and there is nothing we can do to save them

Yses Rob a good theory
but I must admit Ii havenot been on a site where the coins where mainly discs

Hmmmmm ......................... had a few blank non ferrous discs myself annoying to say the least, the sheep pee could be the cause the place i found these coins is sheep pasture land and I have found buckles on this same land and they are very thin and eroded too

i have found pre decimal on naturally very acid soil that were worn paper thin ,i was astonished at how thin they were and in another 50 years would have prolly vanished .
so naturally very acid soil will totally wear them away in time ..

The early Georgian copper coins were made with very 'soft' metal so they wore down easily and quickly. People would usually put their hand in the pocket and 'rub' a coin between finger and thumb, at least that is what I have been told in the past.
