1970 Lincoln Penny Metal Error

to CCF


Well this is what I think:
1 - you should start your own topic for a coin you want to be evaluated. Posting a similar coin that pertains to the original post is permitted if it relates directly back to that post.
2 - NEVER use nail polish remover on any of your coins. it contains contaminates that can ruin your coins finish and any inherent value. You should use PURE Acetone you gat from the hardware store.
3 - We will need an exact weight of your coin down to the hundredths of a gram (0.00g)
4 - Please, when posting images - post them up right for us. When we examine coins, sometimes we need to compare obverse to reverse and having the images up right for both sides makes it far easier to visualize both sides at once.
5 - The pictures you took are very nice. well done on that part - nice and large, clear and in focus with good lighting.

It is a coating of some sort.
What doesn't really matter as it was done after the coin
was struck so it is PMD.

to the CCF and with Spence, more solder than mercury.

I'd agree; it's had some molten metal - probably solder, since solder is deliberately designed to stick to other metals - dropped onto it. Not mercury; mercury would stay liquid at room temperature and smear across the whole surface. Mercury also would probably have all evaporated away by now.

It definitely didn't leave the mint looking like that. See how much wear and damage the coin has seen? If a coin left the mint looking like that, surely one of those hundreds of people who used this coin would have spotted it, would have said "woah, that's odd", and not spent it.

An interesting find, people do some strange things to coins after leaving the mint (it didnt come that way from the mint). The coating can be from using a weak nitric acid solution which removes the barrier that prevents mercury from normally bonding to the cent. Once the cent is coated with nitric acid, it prevents the copper from forming an oxide layer, so it really absorbs mercury at that point. It could also have picked up some solder, but in any case this is just some form of damage with a coating and its not worth any premium.

Interesting. The oxide layer can prevent the bonding of mercury as you can also see in the video. The nitric acid I mentioned is just one method to prevent the copper from forming an oxide layer so it then bonds well.

Mercury unfortunately is known now to be quite damaging to the body and many people developed health issues from exposure. Yet we had exposure besides fish and environment and being passed down through the placenta at birth, such as Mercurochrome, amalgam fillings, thermometers with mercury. Radiofrequency radiation including Wi-Fi exposure of 2.4 GHz for 20 minutes significantly increased (approximately doubled) the amount of mercury released from amalgams of the Wi-Fi exposed group compared to the non-exposed group. Since many of the population has dental amalgams, this becomes a serious hazard that is not being considered https://www.ncbi.nlm.nih.gov/pmc/ar.../PMC4944481/ Now back on track to coins.

@DATA, thanks to put this link for the members here. I have no idea what they will understand?!!. This semi study was done by no medical science personnel. I know this article-study long time ago when one of my residents come to me thinking find the grail. Is tell nothing, was done for med Eng. EMF studies. In normal condition like today with the quantity of Hg we take, the humans need at least 250 years of life to be affected deadly. Do not panic of this.

Now, we have to comeback to our coin. The Hg (mercury) at the room temperature is liquid (till 30 C deg.) then after will start to evaporate. Coating an cent with mercury is very easy task. Cotton tampon, mercury and the job is done. No need of any other things, The alloy in coins in oxygenated alloy, so the mercury will stick on. Any oxide will help the mercury to stick on the metals due to theirs oxygen composition.

Thanks for your theorems.
