Let me do a little internet searching first...if I can't find it, I just might take you up on that.

 

Cool beans. I figure you've got more err, umm, "skillz" to find it online than I do.

 

Chris,
Thank you so much! as for all the comments on my post, first and foremost I pay attention to the ones I have respect for such as yourself, I'm learning as I go, now between you and other teachers of this forum, stressing the term "teachers" to those who have correct info. or can direct me to someone who does, without a doubt I am thankful, as for comments that are shared negativity or positively on what I and others post allows me to get to know you all more on a personal level, which is good, thanks again!

Hope I did not give you short shrift Dottie. I was a little short on explaining. It might have looked a little negative, which was not my intention. Tom

 

Thanks, Dottie!

I have to admit that I sometimes get sucked into the combat zone, myself, but usually in self-defense.

Learning mis information and believing it, it's been the food of many a scorned individual.

 

The striations are more likely to be a planchet issue than a form of environmental damage, The environment caused the different tones, but not the evidence.

 

no sir, I did not take it that way, thank you

Unfortunately, I think that is just a little bit grungy.

Filthy lucre?

Keep looking. Plenty of great coins hiding just waiting to be found......

 

Spendum

 

No. Those are striations which occur during the blanking process. Quite common on some of these but, as with any IKE, the higher the grade the more interesting they are.

 

Hey! That was my coin!

It's uniqueness was that it was struck on a Copper-Nickel planchet whgen it should have been struck on a 40% Silver planchet.

As of today, it's one of three known.

Here's the original image shot by Todd Pollock after the coin was found.





I don't know if it was mentioned in the linked page but after asking if they had anything unusual, the teller pulled out 3 IKE's. Being blind as a bat as far as mint marks go out in the real world, I pondered on whether or not I wanted to drag yet one more 1973-D IKE home to chew up storage space and drag across the country!
With a "Oh what the heck" decision, I bought all three coins and got the surprise of the year after looking closely at the mintmark at home!

It was photographed, reported, graded by NGC and sold to a prominent collector before it ever made it back home.

Sweet coin.



There's never any harm in looking and then asking.
The harm comes when reasonable explanations and answers are ignored in favor of uneducated guesses. Educated explanations come from understanding the minting process and all the different things that can go wrong.

This particular coin was obviously cast aside by some dealer who probably purchased a bunch of raw silver IKE's in a tube not realizing what the coin was.

How it was manufactured?

1973 had a LOT of weird anomalies occurring at the San Francisco Facility and as suggested, could very well have had a CnClad blank tossed in with the Silver blanks.

Remember, there was an unusual relationship between San Francisco and Denver in that Denver usually ended up with San Francisco rejects. This accounts for the various 40% Silver IKE's produced at the Denver Facility. Maybe somebody dumped a few rejected CnClad Proof blankjs into the barrel they thought was intended for Denver but turned out to be intended for Uncirculated 40% Silver Production?

Nobody knows for sure.

 

The striations on the OP's coin aren't on both sides. Is that normal?

 

Look closer as the striations exist on both obverse and reverse of the OP's coin.

Lots of corrosion on the reverse but they can be seen running the exact opposite direction, 8-2 across the moon, from the 10-4 direction they run across the obverse.
