How Do I Make This Gothic Florin Look Silver Again?

Post by detectorman5050 » Thu May 16, 2019 10:34 pm

Found this one down the beach today. It's nice a coin, but the silver is very tarnished due to the sea water.

Is there any method of cleaning that can make it look 'silver' again?

Thanks.

try leaving it submerged in lemon juice or vinegar overnight. Both are mild acids .

I avoid using acids as they tend to etch the surface. Just some metal polish on a cloth will bring out the highlights nicely. ::g

Nice coin. ::g

Normally I'd not touch it but modern silver from the sea is rarely in a collectable condition.

Wrap it in foil, dip it in boiling water for a minute, or until it starts bubbling vigorously and you chicken out, then rub with a cloth. Repeat as necessary.

⬆️What fred said.

It’s my usual approach and Works for me.
2019 hammies. = 115 (including quarters, halves and broken)
Saxon = 1( broken sceatta)
Celtic. = 1
Silver denarius = 4
Gold Roman = 0
Gold ring. = 0
Gold hammered .= 1😀

Aren't you supposed to use baking soda with the foil and boiling water?

Allegedly yes, but I've never found that it makes any difference! :D

I tried several applications of bicarbonate of soda, tin foil, and boiling water. I removed the coin after each application when the water stopped fizzing. Certainly a significant improvement, and the coin actually looks silver now. However there is still quite a bit of black tarnishing left.

I'm surprised that someone who's been on here a while, with plenty of posts, like you have, hasn't considered electrolysis.
That would be my first choice for a coin like that, even though it always seems a bit "hit and miss" whenever I try it. Sometimes there's vigorous bubbling and the muck flies off, sometimes nothing much seems to happen at first. But it seems more effective than aluminium foil and spittle.

Will try electrolysis at some point - I was vaguely aware of it. I've certainly got plenty of 'candidate coins' for various cleaning experiments.

It looked fine to me as found... but if you have to clean it up - just a general question - it was found in an alkaline environment which caused the patination - does that mean it needs an acid to counteract it? Conversely if found in an acid soil, would some alkaline cleaning method be more effective? I can't see that there is any 'cure all' cleaning solution - it depends on what you are trying to remove....

Here is a 1915 silver sixpence I cleaned up using the bicarbonate of soda, and tin foil method. It took repeated applications, plus light brushing with a toothbrush to achieve this.

I think it is quite impressive, as I thought the coin was beyond redemption.

Bingo!
Looks great.
Next stage for me would be a light dunk on bleach-maybe 20 seconds
It will go black and then you can bring the highlights back out with more tinfoil ::g
Mind Sometimes they can go patchy,some areas might not repatinatevwith the bleach :-SS

I found a similar coin - do you actually boil the coin, or just boil some water in a kettle, wrap the coin in foil, and drop it in a cup with the boiled water?

I just dip it in already boiled water simply because I never even considered any alternative. Keeping the water boiling might well speed up the cleaning process but would risk increasing the stress on our local A&E! :D

Thanks - will have a try.

I have to declare something that made me feel bad - but lesson learned:

When I found it, it was caked in mud - it looked a bit gold, and as it was shallow I just assumed it was a £2 coin. So when I got in, I took it to the sink, didn't even turn on the light, and started scrubbing it with a brillow pad.

Before I did too much, I had another look, and saw not Elizabeth II but George V !! rl;

Lessons :

1. Never immediately assume what you have found is what you expect it to be.

2. Never clean in the dark

3. Inspect your finds carefully before attempting any kind of cleaning - so that the technique employed is an approach commensurate to the item.

And this is the coin - the left side is just after I did a bit of brillo-ing, the right side is after a few goes of boiling water, and silver foil. Did it about 4 times eace, and between each either rubbed with a cloth or used a toothbrush.

There is some improvement - but still not great - any thoughts on how to make more improvements with our ruoining the detail on the coin.

(nb The LH picture quality seems worse than the RH, which does not help on comparison!)

Thanks

@sgoody1, I would recommend electrolysis over the tin foil/bicarbonate of soda method for silver.

viewtopic.php?f=122&t=111762&p=988110#p988110

However, I would not recommend my 9v battery method of electrolysis.

Thanks for the electrolysis idea - but in the meantime I have been trying out lemon juice.
Dunked in it for about 3 sessions, 1/2 an hour each time, and wiped and rinsed before placing back in the juice.
The results are below.
I do want to have a go at electrolysis at some point - it will be interesting to see how results compare.

That looks great! I tried lemon juice on silver for the first time recently and I was amazed at the result.

I can’t believe that I haven’t tried it before.

Is my florin now looking too silver? Or is that how it should look?

Could anyone post a picture of what a nice silver florin (or similar aged silver coin) should look like with rental cleaning, to look good enough for a display - or would detectors normally take this kind of coin to the same level that my one is now in?

I guess its each to their own - but I would love to see how other detectors would deal with a coin like this.

Thanks
