Yikes! Watch for these marks on Silver Eagles.

This is precisely why I do not touch graded modern coins. I don't think I've ever seen a truly deserving MS70.

Nothing is considered full proof. Environment is at the top of my list. More precisely, moisture. Good luck.

 

The first I ever knew of these spots was when everyone was looking for the 1964 proof AH half dollars. Coins that looked fine were coming back from being graded with spots or they developed spots shortly after that.

Many believed that shipping and just the change in holders made the spots start showing. I still believe that. My collection of silver eagles have never grown spots and all are still in the original mint packaging.

Something in the silver itself is just waiting to start showing. I have a 95W that looks perfect but I will never remove it from the mint packaging for grading. It's hard not to send it in with the price of PR-70 today.

 

Hi there and thank you in advance for any insights on the eagle. This coin is stated to have a strike through and is graded ms69 in First Strike. It was also stated that this was overlooked by PCGS when graded. Is that even possible since the imperfection is clearly visible with the naked eye. Why would PCGS not designate this as an error coin ? Or maybe it is not a strike through? In your opinion, is this a desirable Eagle especially since it is a First Strike. Also, with the price guide very high for an 86 in First Strike, would $900 be a good deal on this? Or is that imperfection hurting it's value.

Thank you!

 

its probably not the coins but either the holders or a combination of material the holders comprised of and whatever chemical that is applied to the coin prior to being placed in the holder creating a reaction.also maybe a reaction of holder coin material and a 3rd factor creating an acid reaction.just a thought.

 

It’s a Boston coin

 

ANA DEFINITION OF MS-70: "flawless exactly as it was minted, with no trace of wear or injury. Etc...."

Now, in reality, all coins EXACTLY AS MINTED can come with Flaws ("errors" due to planchet or strike). The Major TPGS add under 5X magnification. MS-69 can have no more than two, small, non-detracting marks or flaws. One knocks it out for me. As far as Mint made imperfections, I will grade a coin MS-70 with a strike thru because I mention the imperfection: MS-70, struck thru. Grading is personal, if anyone wishes to buy a coin graded MS-70 with three marks, that's their business.

I've seen thousands of 100% perfect coins using high magnification under a stereo Microscope and florescent light. Trust me they exist; and I personally do not know how both the Mints of the world and Daniel Carr can strike so many of these large, perfect coins!!!

IMO, your coin should have been called a strike thru.

 

Thank you all for your great responses! Very informative and helpful!!

 

well i asked my mom and she told me to quit smoking with my coins when i have a cold or ill get spotty coinage.then again who listens to mom anyway.those spot dont appear to have dierection as if projected.they apppear to grow outward like a chemical reaction or fungus.

 

as well as between the B and the E

 

The rest

The residue is on the metal before it is hit with the die. The residue is "stamped" into the metal deeper than just the surface. That is what the Milk spots are coming from. Trust it's no theory.
There is ways to remove them, I have done it many times.

 

If PCGS is offering a reward still, which I don't know or I have never seen personally, they probably figured it out and stopped offering it.

 

It's borax left on the metal by the way.

 

Could it be gasses from the holder itself ?

 

If it's "stamped into the metal deeper than just the surface", how do you remove it without leaving a pit? Or is your "removal" process actually "resurfacing" (i.e. smoothing) the coin in that area?
