Your comments are clear indicators that you do not understand how to properly examine a coin or to objectively describe it. Here are images of your coin as posted (left) and after minimal enhancement to reveal detail. Red arrows point to scrapes nicks and other damage. I ran out of space to squeeze in more arrows. Members here will help you all they can, but you have to do your part by paying attention and not assuming you "know everything."

I copied your photos, then adjusted the contrast to reveal additional details with Photoshop software. This can enhance visibility, but it cannot completely correct poor photography.

Your coin appears to be and ordinary 1967 Kennedy half struck in 40% silver. It is shown in out of focus, over exposed photos. If you send it to NGC or PCGS for "grading" it will be returned in a cute plastic holder after they've collected your $50 in fees and postage. The coin will be worth exactly what it was before sending it in, because of the scrapes and scratches on the coin. Unless in very high grade, such as MS-68 or higher, there is no collector premium on any 1967 half dollar. Members can give you - free - a better idea of its condition if you will post sharply focused, correctly exposed photos.

They already do --- they call it "MS-62" regardless of the size of truck that ran over it.

Both are post strike damage -- at least from the photos.

Damage and corrosion. Nothing more. Can you (the OP) explain what a "double died and punched" coin is? Can you tell us how mintmarks are made?

We are already in an age-related redistribution of collector coins (and kegs of wheat cents, etc.). Children born 1935-1950, who collected coins, are now dying at an accelerating rate. Without a specific, previously unidentified source, the "hoard" is merely part of statistical randomness. (Humans are sensitive to pattern making - it is one way we organize the world. Pareidolia is one kind of the same class of human organizational actions.)

No. And identification does not matter. The altered ASEs look like the real thing -- just as an 1909 with glued on S does.

Might also be something made by a colorado counterfeiter. It produced altered ASEs in the past, so why not again?

Well --- not really -- I skipped around a bunch and yawned some, too.

It seems a bit too long and unfocused. There are also several mistakes, misdirections and loose-ends, but that happens with this sort of promotional item.

Better if that was a "run-away sentence" .....

The OP must have purchased a "Word Grab-Bag" from a U-Tube coin error video.

Is he telling facts that he knows, or simply spinning a story abut some assumed "stealthy hoard?" His price changes can be checked for reality, but not his "reasons" for them....if he has any.

Damaged in both posts....

Now think....why would such a "nice" coin not be in a legitimate TPG holder with a cute smiley-face sticker? The contrast has been exaggerated so the fields look black and relief almost white - not normal for a coin of that era, except for a few carefully maintained pieces.

Was the US occasionally shipping US coins to Mexico? This letter seems to imply that....

Italian States LUCCA Scudo KM# 60. 1751. Obverse Legend: LUCENSIS RESPUBLICA ( Republic of Lucca) ; Reverse Legend: SANCTUS MARTINUS (Saint Martin). Reverse depicts "Saint" Martin on horseback cutting his cloak in half to share with a beggar. (The horse turns to watch the action...probably thinking "Better that cloak than me.")

Without hard evidence, it's just rancid bologna.

Wish I could have published this....it wipes out all the previous copy cat stuff.

They were all pattern pieces whether shiny or not.

Roberts had more opportunities to preserve historical specimens than did Leach.

Hmmmm.....I wonder the same thing, just the other way around.

Frank Leach had replaced George Roberts as director. Each might have held different views on pattern pieces and each might have been influenced by unknown conversations. Leach "should" have ordered the S-G HE and Pratt HE patterns put in the mint cabinet of coins, and he had previously acted to preserve the $10 knife edge patterns, and small diameter DE, but..... we'll likely never know.
