Silver is an excellent conductor, better even than copper. Electricity and magnetism are closely associated so moving a magnet across a conductor (in this case the coin) will induce electric currents called eddy currents in the conductor. These currents produce magnetic fields of their own which will tend to oppose the motion of the moving magnet so creating the diamagnetic effect. It is the same principal that causes a magnet to descend slowly if you drop it down a copper pipe. Inn theory it ought to work with the pre-1860 copper coins, too , as copper is also an excellent conductor. Here endeth the physics lesson! Some 1918KN pennies have 'crow's foot' error by the King's ear which makes for a bit of variety and something else to look out for (as if there weren't enough variations to look out for already!) Thanks for the video, Paul - some nice coins on show! 🧡
Great Video, I’m not an expert but I think maybe the Roman coin at 12:44 could be a follis coin of Emperor Constans which would put it in the years 335-337AD.
Hello Paul, coin co£in here , just viewed the final part of your marathon 12 part penny hunt, great fun. I hope you received my letter with some information on modified effigy penny. Your coin channel really is the most entertaining with your witty banter and humour. After much difficulty I have managed finally , to register! Thank you.
Some lovely condition coins in Pete's pre decimal collection. Great information on how to test for fake and silver coins 😊👍. Your yellow balls are very handy but a bit messy 😆.
search for slide test basically the same thing just hold the coin on an angle and drop a magnet down one side on silver it'll slide down slowly not a 100% accurate test as other metals can have a similair effect I usually do a ping test too but displacements probably the bet test
Thanks for that mate very interesting that 1919 fake coin wow and the way you tested the coin and that is a way to test silver coins nice one.Until your next video stay safe.👍🇭🇲👍
Brilliant Video and great coins I would even say the prices for the 50% coins should be a bit higher due to the price of silver Shame about the 1919 KN what a find that would have been!
Hi Ian, the silver threepence had become unpopular in England because of its small size, but it remained popular in Scotland. So silver threepences were produced as well as the brass ones from 1937-45 (and almost all the 1945 examples were subsequently melted down) The silver ones and brass ones were demonitized in February 1971.
@@CoinPatrol Gosh,(born 1956) I got 3d pocket money and in 1966 it went up to 6d which, would buy a bar of Cadbury chocolate, I never saw a silver 3d in circulation or a farthing last minted on my birth year, Black Jacks were a 1/4d each but in my time were 4 for a 1d.
You should look for the dot under magnification, it looked like it might be a very early die set for the dot. I thought I could see a very slight shadow where the dot would be.
Since watching your Penny vids I started a date run on pre-decimals. It's a great way to build a collection from zero value coins. Loving all the info. Come on Pete get them in an album 🤣😎🍀💜
If I gave over coins to anyone to look through , I would photograph/video the numbers and condition of them first in case there was a million pound coin in there , (and I would know the valuable one, as that will be the one missing when they are returned )
New subscriber here , Great video , love learning from you. I have a very old whiskey bottle full of 20p , do you cover valuable 20p thanks in advance .
Hi Jayne. The only rare 20p ii the undated one. No date on the heads side and no date on the tails side. This one sells for about £50 Thsnks for the sub
@@CoinPatrol thank you so much , I’m going to go through the hundreds of old pennies now to look for a 1919 kn lol , I have 3 cardboard boxes full from my great grandmothers house. Full of cobwebs and spiders 🤣🤣🤣🤣
I had an 1880 victoria 3 pence with litle worn like the 1902 edward the 7 'th one you shown in the video ,sadly got stolen i paid south african R50 rands for it back then ,would be worth a pretty penny i guess right know😢

Another Great Video Paul 😊👍Thanks for sharing 👍
cool bag of coins i cant wait for another box of old pennies
Great job sorting through Pete’s coins. Interesting collection. Many mint marked One Pennies. Lots of old silver coins. Thanks for sharing.
Great Video, I’m not an expert but I think maybe the Roman coin at 12:44 could be a follis coin of Emperor Constans which would put it in the years 335-337AD.
Thanks for teaching us... and for sharing the science!! 👍😁
Used to rattle your change in your pocket when felt nervous, no wonder those old coins are very worn! 😄
Some nice coins but I find it really hard to believe that you have friends 🤔🤣
😂 who wouldn’t be friends with this legend?!
@jwbricks He's a good guy but please don't tell him that I said that 😂
Great coins thanks CP keep safe
i do so like the design on the 1923 florins.
very interesting information on the silver coin reacting to the magnet, i have not heard of that before.
For Pete’s sake! 😢 😂 that was a cracking video CP
Cool batch of coins.👍👍
Fancy shattering Pete’s dreams on sitting on a nice little nest egg 🪺 💰😂
Some really nice coins nonetheless
Great stuff 👍🏻
Very nice silver coin’s. Real shame about that fake KN Penny. Very nice collection 👌👍
some very nice coins as well as a lesson on silver and fakes

Very nice Silver coins
Nice coins and thanks for the interesting information Paul! 😃
Another good and interesting video Paul. Please do more of this type of unusual coin related videos...
Thanks for that mate very interesting that 1919 fake coin wow and the way you tested the coin and that is a way to test silver coins nice one.Until your next video stay safe.👍🇭🇲👍
Cracking video mate, learn something new every show. Some stunning old coins there Pete.
Very enjoyable video. That 1919 kn was interesting maybe made in China.
Great video. I was in a charity shop today and saw the Jubilee and Churchill crowns, they wanted £10 for the two.
They're worth £1 each!
A great video and a great collection Pete has there. That not-a-1919KN... a very strange 'coin'. Does look to be a space filler.
Nice collection there, let’s hope they don’t stay in a plastic bag forever !
Brilliant Video and great coins
I would even say the prices for the 50% coins should be a bit higher due to the price of silver
Shame about the 1919 KN what a find that would have been!
Absolutely Fascinating to watch along side your search, What year did the thrupney bit change shape Paul?Shame about the 1919KN

Roman coin is a 4th century AE4 - "Gloria Exceritus" type. Generally common.
Paul absolutely great coins there love it....

9:51 I have a 1922 Florin in a Very good condition ( Has no scratches or faded areas) How much do you think that would be worth? cheers.

Great search mate 👍
Question! I have a 2010 and a 2012 five pence coin and the 2012 is noticeably thicker! Why is that? Thanks!
Some pretty decent conditions on the older pre-decimals. What a great bit of info on how to test for fake and silver coins. 👏👍🧲
1933 sixpence turns up... "Shame it's not a Penny!"
.. thought the 1930 1d.was a rare one ..
blimey your knowledge how do you remember it all im just starting to collect in my old age already confused
If I gave over coins to anyone to look through , I would photograph/video the numbers and condition of them first in case there was a million pound coin in there , (and I would know the valuable one, as that will be the one missing when they are returned )
I actually have an older florin from 1923 I think and it's not as worn as it usually would
Very interesting. Yes, please do a video with your yellow balls, I'm intrigued! 🤔☺️
