What should I do with this IHC?

Juke Box?

:secretid you mean Juke Box instead of Junk Box?

I wanna see where this IHC ends up after being "corrected" using the available advice.

Most of this is way over my head also, and I am still trying to soak most of it in. I plan on "experimenting" this week and will definitely post photos of the outcome.

I really did not intend to start a firestorm with a coin some of you think should be in a junk box! However, it will be good to work with this coin, so I can learn what to do with my better coins that have similar issues.

Again, thanks for all of the advice and I will put up pictures later this week.

 

Good deal, take your time and don't rush the process, it took years to lay down the corrosion, it may take a bit of time to remove it.

When I sifted through the ashes after the firestorm, my conclusion is PVC is not the same as verdigris, both are harmful, but if PVC is caught in time, it might be reversible.

Good luck.

 

I dont have any questions,but thank you for pointing this out.it is exactally what I stated.Chlorine from PVC created verdigris.

we are talking about a indian cent,not an ancient coins

U.S. coinage=mainly 80% of them stored in PVC at one time,as there wasnt much more to store it in

PVC=creates verdigris you even stated it.chances are if your U.S. coin has it,it was prob stored in PVC at one time.if it is slimy & dark,it was in PVC

Other member stated if it was in a album,it could be produced from air & salt,yes it can,but the color would be very light green.like on your water heater.dry because it is more salty & acidic,and little chlorine present.

depending on the color and texture of it,is how it is caused.

there are countless shades of green from dark to light

and there are countless textures from very slimy to acidic dry

if anyone else decides they want to keep going round & round,lets go.I dont need to PM anyone,I am highly educated,and can back up what I say,and have no problem saying it in public.if you want to get ultra technical,down to the atom countencil:

for U.S. coin collectors,it is alot easier to think that green is PVC,chances are thats what caused it for your U.S. coinage.

albums verdigris will be light green and usually very dry,maybe slightly wet.

PVC verdigris is very dark,and slimy.

and there is a good chance that your album verdigris came from a coin that was stored in PVC and it spread like grass across the album,and that would be why it is on a large section of coins,and there are others that are affected.

as a coin collector,if i see verdigris i automatically think PVC,and it works great thinking that way.as a U.S. coin collector in general,most do not need to know the chemical makeup,as they dont understand,nor do most care.so if you always keep the two as one.it is one less thing to worry about. its bad either way.

Now to the "PVC" on coins.when you see silver and it looks wet,kind of like
Vaseline watered down a little bit,that is chlorine from PVC,if the coin was copper it would turn green.its that easy

 

lol
This is funny in some ways.
It's like a global warming debate

BTW, no more chemist's are allowed to enter this post as they keep entering and confusing me even more...
So far I've got this:
1. PVC is bad for coins
2. Verdigris is bad for coins
3. I don't want either near my coins

 

that's all you need to know

 

Thank you:thumb:

 

Mike, Welcome to the forum.

PVC ( nonplasticized) does not sweat. Plasticized PVC does. It has migration of the plasticizers to the surface where it can leave the polymerized structure of the PVC matrix (sweat?). PVC coin flips where high migration rate plasticizers such as Phthalates were used does have migration which can initiate the coin damage. It is difficult to find documentation on plasticizer migration data in flexible membranes, but but here is one source concerning PVC membranes that is quite similar to the PVC Flips, except it has no concern with transparency.

http://www.geocheminc.com/pvcfaqplasticizers1.htm

You can see that the loss of plasticizer from the PVC is highest in the first 5 years and then stabilizes. The smell from new Plasticized PVC is from the plasticizers, not from the PVC.

Some of the newer PVC coin flips do not use high migration plasticizers, and as such imply they are safer, but can not use the word archival.

man... you guys are a bunch of nerds... but thanks for the info!
:mouth:

 

:high5: :computer: :hug: :goofer:

 

I thought all coin collectors were nerds?

 

That's what my wife tells me... :crying:

 

Yea I'm told that too about all coin collectors. Then the wimp runs away as I chase him to give him a beating

 

Write what you want Mad.Outcast since you aren't following science or logic and I refuse to continue to participate in a circular debate on the topic. I don't know your background, which is what you have written on the boards, but I know mine and it is more than somewhat significant with respect to chemistry and science in general. If you want to know more of my background simply send me a PM and I will fill you in.

For everyone else; use your brains and logic and decide for yourself. Even send me a PM if you want. I will not let myself be drawn into this further.

 

Yes, it seems to be a waste of a good keyboard.

anybody can say what they want.science is also a part of math,and if you look you will see 2+2=4 it also equals addition,numbers,and whatever else you see...... sometimes whats logical,is not what the reality is.and sometimes what people are taught,is not the reality either.

added: I try to teach in a basic form,as teaching isnt always about teaching,its about making your students think for themselves.


added again,also,a college degree,doesnt mean anything,other than the fact,that you paid someone to teach you,what is free & readily available everywhere you look.and in the end,you get a bill,and a piece of paper that says you paid,to have someone walk you through a book(s)

 

That's a whole bunch of Granola!

The fact of the matter is that you shouldn't be teaching anybody.

Chris

 

Ha ha.and people said we would never walk on the moon.

 

LMAO!

Anyways, at the end of the day, it looks like PVC gunk to me. It appears 3-D-ish. In my experience, that's PVC gunk.

I have plenty of colonial coppers that have their share of verdigris, and this specimen doesn't look like it has verdigris to me.

My two cents.

 

lol...
