Silver shilling damage/cleaning?

Post by LloydF »

I found this silver shilling pictured, it's 1924 so only half silver.

All down the left edge you can see damage / pitting, this is the same on the other side too(same edge) is it worth trying to clean it etc? Or is there any other way to improve ie. Would electrolysis help or is it just damaged, accept it and crack on finding a better condition one? It is surprising as I found a 1938 sixpence on the same field and it came out perfect.

Any advice would be great!
Thanks!

It is hard to guess what is under corrosion like that. I think it should not be too pitted. Coins get different patinas and corrosion for no apparent reason, depending on how they are lying, on soil structure etc. Even right next to each other they can be quite different. I don't know what is best for half silver for cleaning , light acid should take off copper compounds but leave any metal intact if you are bringing it back to clean, or electrolysis , you have to wash off after immersion in anything or copper might flash onto the whole surface and that is a hassle to remove. Hopefully someone else will give a better reply ::g

Corroded 50% silver can be a right swine to clean up. Whatever I do most of the beach ones never look right again. I have never tried electrolysis on them though so please do let us know how you get on.

The middle seven are 50% silver while the rest are sterling, which do clean up a bit although it's seldom really worth the effort. ::g

Try lemon juice (plastic squirty one) from the supermarket.

Here's some results of it's use on similar silver content coins.

I now use dilute acetic acid (fine crystals obtainable on-line for about £7 per Kg.

Best way I have found to clean up these types of coins, as they have very little to no value anyway, is Harpic 10x toilet cleaner. wear gloves and use neat and a gentle rub between your fingers will do the job. rinse off under cold water when done. ::g
Do not use on Roman coins or anything of value ::g

Hello LloydF
I dug one of these up about 2 years ago and it was in worse condition than this. I was told by someone it could be fire damaged from when the farmers used to burn off the stubble etc. Just a thought though.

I would do the following:
Get hold of a 9v battery or old transformer (I use an old Hornby railway transformer)

4 x Croc Clips, 2 x wire, 1 x Stainless Steel Spoon, Half Pint Glass of very warm (not very hot) water

Then add:
3/4 x teaspoon of Citric Acid
1 x teaspoon of Salt
Stir till dissolved

Wire the items up and immerse for about 5 mins. then see what happens.

I do this on most of my very bad silver finds and it seems to work each time. It won't get rid of the pits though.Good luck and please let me know how you get on. Thanks

PS Make sure you wash glass after in very hot water & soap and DON'T use the spoon for anything else!

Thanks for the tip.. Here are the before and after of the Shilling that I've just done following your suggestion of Lemon Juice and used a toothbrush to lightly scrub it in after soaking for 1hr

When I used to beach detect on a regular basis I found the best way to revive grotty silvers was to barrel them. Note the grotty bit, nice stuff should never go near a rotating barrel.
I tried ammonia, silver dip, vinegar and lemon juice, hardly worth the effort on what is essentially scrap silver.

Scrap silver? I think of it as future treasure and I also think the pictures above show it really was worth the effort.

Here is a George V (1914) Sixpence found yesterday in the before and after state of immersion in lemon juice for 30 mins and a light brush with a toothbrush.

This is favourable result for those wishing to retain a little patina.
