MS 70 on 1960 Copper Pennies

[WinstonWare]

After reading recent posts I wanted to see if I could make copper turn color with MS 70. I ordered 1 roll of 1960 BU cents & 1 proof 1960 cent. I believe that these cents have the same composition as Indian head cents and I feel comfortable assuming that they have not toned and later been shellacked.

 

The directions on the MS 70 bottle read, "MS 70 is not a dipand will not work by dipping your coin. Apply MS 70 directly to coin or soak a Q-Tip in MS 70 and gently apply to coin. Allow a few seconds for MS 70 to penetrate the contaminants on the coin then gently massage the surface of the coin with a Q-Tip which has been soaked in MS 70. Thoroughly rinse coin in water. NOTE: When using on copper do a few “test coins” to become familiar with how product works.”

 

Here is a picture of the coins before. I didn't end up using all of the BU cents in the picture.

 

The coins were allowed to sit with MS 70 on them in the following order from left to right: 1 Minute, 5 Minutes, 10 Minutes, 15 Minutes, 15 Minutes Proof. The five off to the side were not used.

 

This picture is accurate. I couldn't see any differences.

Are you sure thet's not betadine or maybe pizza sauce?

." I believe that these cents have the same composition as Indian head cents."

 

 

You are incorrect. Try again.

 

 

BU red copper is NOT a good test subject. Reread the old MS70 posts for hints.

Back to the lab!

All the proper ingredients, but without the recipe you won't have the results you are seeking.

I suppose, if someone placed a couple of eggs, flour, oil, sugar, salt in front of me and I was to bake a cake I'd have a difficult time without a recipe to follow.

 

TRU(th)E?

C'mon guys, I'm trying to make an entertaining and informative post here. I went out of my way to order all this [embarrassing lack of self control]. I spent an hour or so today farting around with all this stuff. I was going by the coinfacts site metal content:1960 1890 IHC they appear the same to me.

Could you please tell me what you think a better test would be and why? I would greatly appreciate it.

 

Thanks Winston

-- "farting around" --

 

I've heard that this is the critical ingredient; but it must be added in correct proportion to the other chemicals.

You really need to try this on some MS Indians or coins with thr 95% and 5% compistion. Good Luck!

[WinstonWare]

Bruce,

 

That's what I was thinking. I really didn't want to get into making this a $100 + experiment & I was also interested in getting newer coins so I could assume that they hadn't previously been toned. Did you get a chance to look at the links I posted for 1960 cents and IHC cents above? Their composition look the same to me - 95% & 5% tin zinc. Appearently some disagree. Do you understand why? I'm not clear on this.

 

Thanks Winston

[Bruceswar]

I took a look at the links and why both are 95% and 5%.. The 1960 is what percent tin? and what percent zinc compared to the Indian?

[WinstonWare]

Yes, good point. Not sure. I'll have to dig deeper into that.

[Bruceswar]

I will be curious to know the results on that.

[truthteller]

Yes, good point. Not sure. I'll have to dig deeper into that.

 

 

HINT: The more the oxidation, the deeper the blue color using MS70.

 

Another HINT: Red BU coins have very little oxidation coating.

 

Still Another HINT: Use a BROWN UNCIRCULATED cent from 1930's(Same composition as IHC)

 

And Yet still Another HINT: Use two or three coins for comparison.

 

 

This should cost you under $10 total.

As Truth said: they can't be red BU.

I think you'll want to repeat this experiment on RB or BN copper that yet has a lot of luster. That's the mistake I made, applying MS-70 to RB copper, and having it turn blue.

Ah okay. Thanks for the helpful hints guys.
