Toasted coins?

Post by MT83 » Sun Dec 01, 2019 7:09 pm

Hi all, have only been detecting for a short while, I haven't really found much of note yet but nether the less this has not deterred me from enjoying the hobby
I am desperate to find a nice coin but so far no joy, I have however found these 'coins', all in the same field, I can only assume they are coins because they are in really bad condition and I cannot see anything on them at all.
I have tried some DIY electrolysis because I thought I've nothing to lose which has cleaned them up but still no detail.
'Coin' number 3 isn't too badly pitted or anything but is completely smooth.
If they are coins why are they so toasted, is it because they are a couple hundred years old or is it to do with soil conditions, i.e.acidity maybe? It's so disappointing to see this coin in the ground and then pull it out only for it to be rough!!
Any advice will be greatly recieved!

They look like standard worn Georgian halfpennies, although thay could even be a ruler or two prior to that. Look at the edges of the coins and see if you notice anything odd, like a groove running around the middle. If it's there it will narrow the date to 1799 for the larger one and 1806/7 for the other two.

Thankyou for the advice, I must admit by measuring them I thought that they might be half pennies, I have now looked at the edges and I can see no groove.. It's so frustrating that the only 3 coins I have ever found are all in such bad condition.

I would keep water away from copper coins and just rub them (when dry) between your thumb and forefinger to try and enhance any detail remaining.

Ah well, nothing for it but to get back out and find something more readily identifiable then! :D

They can be frustrating but Georgian coppers are more likely to come up toasted than recognisable. You could try gently rubbing them with fine wire wool. That will sometimes highlight sufficient detail to recognise the monarch.
It doesn't seem five minutes ago that I was in exactly the same position as you are today. Experience will tell you which coppers you may be able to recognise with a little work and which go straight in the scrap bin. That's how it is.

Exactly my philosophy. It's difficult to resist cleaning but they're really at their best without the water. A certain amount of mud allows the detail to show through.

Don't worry about them being rough and illegible, Georgians are everywhere and they're almost all like this. Makes the silver Romans and hammereds all the better when they pop up!

It's frustrating to have coins that can't be id'd, and like others say I would also generally leave them alone, or at most rub down the surface without cleaning, as in fine sandpaper or wire wool etc. I think soil conditions are very responsible for them being pitted, because where I have detected (southern europe) often five hundred year old copper comes out of the ground very detailed and unpitted usually. Other times copper based coins will have a hard intact patina, almost like stone. I think bronze behaves differently depending on its alloy. Usually coins that are pitted come from humid farmland where I detect - watered or low lying, with fertilizer used possibly. You can try to ID them all the same, but once you find more intact ones often they tend to just get put to one side, which is a bit of a shame also. If you want a good range of coins to compare to there is this site

here I chose copper to your dimensions, advanced search allows a different choice of parameters. Weight will be out a bit for corrosion, but at least you know that used will be minimum and so exclude lighter coins. Also I always get confused when people say Georgian, which George !?

MT, It's frustrating isn't it.. Personally I think years of chemicals/fertilisers/weed suppressants going into fields alongside different soil make-ups will adversely affect mainly copper alloy coins. Some of the fields I detect in (In fact most), coins come out barely recognisable. Been picking up a few small Romans lately from one field in particular and they are in really bad condition. Other fields in my permissions and different areas I detect in don't seem to affect them so much. Been looking at an area recently which is very chalky, and coins have been coming out not too bad. Silver doesn't seem to be affected so much, and the one (small) piece of a gold ring I picked up recently didn't look like it had been in the ground at all.

Are you questioning my origins fred :D

It has just been a while since I lived in UK and so I'm not that familiar with the term - I always looked back and found George VI and stopped there , because it just seemed silly saying Georgian to cover over 200 years of history. :D

good coins are only likely to come from rivers as thees no acids or contaminants

heres 1 from the thames in mint condition

occasionally you may find 1 on a field but theyre mostly shagged

Does the Thames still have oxygen in it 8-| ( and by coincidence there is Dirty Old Town drifting through from next door :D , though I guess water quality has a lot of attention nowadays) . We used to catch eels and perch, I guess they are still there, maybe under mud coins are protected also ?

Nice coin ::g


Pengles, where I find good old copper based coins is on higher less cultivated ground. The best come from limestone / chalk areas, as well as shale with little topsoil. Pretty much away from industrial areas for most of my detecting also.

Hi, i have posted this before, best thing since sliced bread,I use this on all BRASS-- COPPER--SILVER--GOLD you name it one thing you don`t use it on is steel
Have used it on hammys gold rings with stones set in and silver rings silver chains gets in nucks and crannys also the answer to your question is buy this stuff, it is called SAFE PICKLE but don`tell any body it`s our secret, don`t use it on good copper coins you want to keep.
You can get it on the net got mine from Fle Bay.
How i use it is to buy a slow cooker about £13.00 this has a pot inner also you can warm it up if you want works just as well cold i use this for all my small items, then for big copper and brass items i use a big storage box 2`2` and 2` deep make a batch in that it will last forever, once you have left your bits in for a few mins take out dunk in water wipe off dunk again if need be.
I go to a lot of auctions and buy old blow lamps and big items of brass and copper drop it in 5 mins
job done, use a piece of wood or plastic to remove items hope this helps.
Regards Deepdig.

Thankyou everybody for all of your advice and encouragement it is very much appreciated to A newbie like me. One thing that I have learnt in my short time doing this is that patience is key so
I shall continue hunting for my first reasonably detailed coin, I suppose the good thing is that I'm finding them even though they are trashed. On to the next hole!!!

Thanks deepdig I will look into that, worth knowing for future finds.
