Reaching out to our English friends

[Ronstar]

I’m posting here hoping one or more of our English friends may help with this.

Yesterday I dug a 1957 Schilling which appears to be England rather than Australia in origin. The coin was in the no more than the 7” range and most probable at the 5-6” depth. The soil is a dark rich color and as its a city park no to little fertilizers or herbicides are applied. This coin came up and for all practical purposes should be silver in that there was zero discoloration. Google shows the coin is made of a copper nickel mix therefore there should be that dug coin look rather than near pristine.
I can find no indication as to whether there were any minted that were “silver proof”. If anyone “across the pond” has any reference material and could find out if any of that coin mintage was made other than copper nickel I would truly appreciate it. The coin measures and weighs correctly.
Thank You.
Coin is on the right in the pics and one photo of it in the plug (I pulled it out slightly for the photo)

Nice find!! Looking forward to what you hear about it from "across the Pond"!

Well so far no responses and I cant confirm or deny this thing is silver……

Ron, I researched one I found a few years ago and 1947 is the last year they were silver. As I recall nothing else popped up indicating silver proofs or the like. One of those ??? finds! HH jim tn

Jim, I saw the same info and ‘47 as last silver. I have no idea how this came out looking that shiny unless someone had a way to shove that coin down a small slit within a few days of my finding it. I have not been up to the coin store to have it looked at as of yet. As soon as we unfreeze here I’m going back to that corner and working it out to see if anything shows up.
Thanks for looking it up.
