1860 O Seated Half Dollar Strike Though Error

I'm skeptical. Would there not be some indication of the strike through showing as a weakness on the obverse? Also the reverse indentation edge seems almost too clean. I would expect there would be some flow lines or disruption from the mashing together of metal.

My guess is that it is contemporary PMD. Someone cut/shaved off part of the host coin, then expertly cut out a matching 1/2 dime size piece from another half dollar coin. These two pieces of coins have then toned together over time.

Edit: Oops, just saw the weights posted. That throws a wrench into that theory.

As the weight is correct, that would mean the density of the overall area is somewhat heavier pre cubic millimeter of the coin. Also while both planchets are the same metal the overall hardness is not the same, hence why Dimes, Quarters, half dollars and Dollars are struck at different tonnage. This coin is going into PCGS Monday under express, as its real from everything I can see and view on the scale and under a stereo microscope. As a real 1860 O seated error "this would fall under a huge error" it will fall well above the $10,000 regular value submission.

Again, I understand questioning all errors, I just can't find an issue with this piece in hand! The coin is and if found real it will be an MS grade coin. The coin has no tooling and the reed count that was sent to me is correct for an 1860 O Seated half.

i really hope this thing is real. it would be one of the coolest "errors" ever.

im looking forward to the follow up! this thing is a lot of fun to ponder over.

What a neat opportunity to handle this likely intentional error. Keep us updated on the outcome, both grade and sale price!!

There are some wicked looking error coins there twohawks. Wow, what a collection in one grab. I'm fascinated also by the look of that gunmetal Indian head. Thanks so much for sharing!

I am curious to know if it possible an XRF at the least for this coin. Basic I will perform an ESD/DSX. I never see one like this and also fake in this kind. The tarnish it is not realy correct from the point of view we know, this doesn't mean could not be.

Great. twohawks as I say. Never see one like this. After 20 years looking for fake or altered intentional coins, never see one as yours.

It is unique for me, For this series I have 15 and no one doesn't fit one point closer with this. Hope they perform the tests but I doubt them in the last time without fees.

My forensic test from your photos show the normal design with minor variation which are in parameters for the many strike.

Hope to see good results. Great coin.

The correct weight of a real seated half is 12.4 grams, the correct weight of a Half Dime is 1.24 gram's, with a combined weight of 13.6 gram's. That is plus or minus .04 gram's normally. BTW I think this is a WB-3 not 2 as the date has a much thinner top of the "8"
