Pee results...for now, anyways

I want to clarify at the onset that I am not obsessed with urine, but my curiosity was triggered by the coin @HookFynn posted on the other forum...and @paddyman98 thought it looked like toning from urine.

After 4 experiments at attempting to achieve similar toning, I have failed 3 times, 1 last experiment ongoing, but I am not hopeful of success.

Here is the before obverse of a 2019 zincoln.



I treated it with a solution of 50/50 urine and white vinegar...turns out it is a double acid treatment, here is the result from overnight.



One drop of solution, the cent was on a slight incline so it ran down to the bottom of the bust. Epic fail to tone.

The second coin before obverse, a 2019-D



...and the after obverse shot, treated with urine only and left to air dry.


Once again, did not tone like the other coin from the other forum, another epic fail.

Now, you can make the case that strength of solution and a different time duration might give different results.

Regarding the 4th experiment ongoing: I will keep everyone posted.

Oh dear and I thought I had seen it all.

 

In the name of science (& perhaps numismatics), you are to be commended for your thought process & research execution, in search of an answer to this vital question!

...and thank you for that, lest we all be looking for that particular stain pattern (or avoiding all 2019 P & D cents at all costs!)

 

I hope @paddyman98 doesn’t do any metal detecting around your place!

 

Part of the issue I think is in the past we have described what have been called urinal coins. So that means they were exposed to water, urine, urinal cake chemicals, and whatever else made it's way into the urinal. Those combinations could cause very different toning.

 

i think you need to let one "dry" for a few
months and see what happens. maybe i'll take that challenge up in the name of "science" and see what happens

 

try cat or dog piss.....they kill my shrubs,

 

reminds me of a new photography called "nutscape" look it up, rofl

 

Please read some science before experimenting. Acid REMOVES toning back to bare metal. Then the bare metals reacts with environmental chemicals for the staining /toning/corrosion. The salts that remain on the coin or environment can over time ( wks , months, etc. can cause the discoloration.

Also urine isn't a standardized product, even from the same individual person. Some eat food which can cause an alkaline urine ( generally those who get stones), but also a varied diet can be now or not now. You need to test your urine if you are really doing this for science each time before the experiment.

If it is just for laughs, it is better not to go that direction.

So its come to this?

 

So we failed the pee test? that like your left foot.....just not right....

 

The fourth test came out like this:

 

Every one is doing this test wrong. You have a few beers and throw the coins on the ground and pee on them. After a few weeks or months you check on them.

 

And here I thought you were an over the road trucker and the ICC was 'checkin' on down the line'.........

 

Gives new meaning to golden shower. I know people that have aged copper weather vanes and garden stuff by urinating on it. Cat piss is really strong stuff and will crust it up in a hurry. Leave a couple coins in the litter box for a couple weeks and see the results

 

I've heard stories from TPG graders about these sorts of coins showing up.

 

That's FUNNY!!

 

Remind me never to ask Bill....hay buddy can you spare a dime
