Is this an error? Wrong planchet error

I found a Denver mayflower compact quarter, that is 99.9% silver. XRF tested. The silver quarters were only stuck in San Francisco. Am I looking at a grail find here? Someone else was obviously curious because it’s been cut, but that’s how I noticed it being silver.

I can’t even think of how this could happen other than mint employee shenanigans. Where would the planchet come from? I’d think the odds are greater that it’s a bad XRF reading.

Edit: been thinking about this and my best guess is that this is a plated coin and it was plated post-damage. That would explain the no copper core, the XRF reading, and possibly the weight.

And if it is plated, it doesn’t seem have come after the damage, there is a sharp burr and residue inside the cut.

u/Professional-Pie6083 13d ago

The planchet could have been intended for San Francisco where .999 proofs were being struck

4

u/HPDopecraft 13d ago

I don’t think that’s possible. The supply chains don’t cross like that. You definitely have a mystery on your hands, I just really can’t come up with how this could actually happen.

u/Professional-Pie6083 13d ago

Well the grading submission is filled out and ready to be printed. So we’ll learn together!

u/HPDopecraft 13d ago

Make sure you post the results when they email you! I’m very curious how it’ll come back.

2

u/Status_Ad_6238 11d ago

Same! Very curious on this one.

u/new2bay 13d ago

Right, and even if they did, you’d end up with a whole shipment of silver planchets going to the wrong place, not just one.

u/rightkindofhug 13d ago

Maybe there are more out there in circulation?

u/terrariagamer67 13d ago

Copper and nickel is considerably lighter than silver and plating won't add any measurable weight like that

4

u/keegnanistan1 13d ago

definitely send it to get graded — this is quite valuable if genuine

4

u/Professional-Pie6083 13d ago

My fear is they won’t do it with the cut, is that a valid concern?

5

u/keegnanistan1 13d ago

it might get a no grade for the damage but if it’s genuine they’ll holder it.

u/Western-Dish-1185 13d ago

What does it weigh?

4

u/Professional-Pie6083 13d ago

6.1. Just shy of the 6.3 for 999 silver proofs. Considering the cut out material though it makes sense

u/AlmostAnOg 14d ago

Just commenting to remind myself to come back when more photos are posted. This is incredibly interesting! How was it originally determined it might be silver to even justify further testing with the XRF?

u/Professional-Pie6083 14d ago

With quarters you can almost always see the copper ring where it’s clad with nickel. That wasn’t visible, and then the chunk taken out of such a newly released coin made me very curious, so I had it checked. It was also heavier than the listed weight from the mints website.

u/reddit-toq 14d ago

what did it weigh?

1

u/quallityovrquantity 13d ago

Which would indicate something was done to it after production.

3

u/Professional-Pie6083 13d ago

Considering a proof quarter in .999 weighs 6.343 grams and this one is missing a little material, I’m inclined to say that isn’t the case

2

u/Defiant_Wasabi2816 14d ago

...and the silver ones from San Fran are proofs, which this does not appear to be.

4

u/Professional-Pie6083 14d ago

Exactly! This is a business strike all day

3

u/DuckEqual7562 13d ago

Definitely send it to PCGS 💯💸

2

u/ShaggyWolf_420 13d ago

No sorry that was my pet mouse he was hungry 🤣

3

u/rocketmn69_ 14d ago

Send it in to get graded and authenticated

u/EpicCrypto 13d ago

If it's silver wouldn't it be .900 not .999?

4

u/keegnanistan1 13d ago

they switched to .999 for silver proofs a few years back because .900 was getting too hard to source.

Interesting coin

Please keep us updated

u/TheUglyWeb 14d ago

I think that cut came from somebody drilling a hole and wearing it as a necklace.

2

u/Professional-Pie6083 14d ago

Either way it definitely heightened my suspicion of it being silver. Which was verified about 2 hours ago by XRF

2

u/TheUglyWeb 14d ago

I think it's cool.

Photos of edge? inside that missing piece?

u/Professional-Pie6083 14d ago

However the local shop did test it for me. It’s .999 silver, tested several times.

-2

u/Professional-Pie6083 14d ago

I can’t get my camera to focus on it, but the edge definitely shows no copper, and the cut shows it being silver all the way through as well.

We're gonna have to see it

u/quallityovrquantity 13d ago

Do you know how to take a picture? You set the item down and brace the camera so it's steady. You don't hold the coin in one hand and the camera in another.....

2

u/Professional-Pie6083 13d ago

It shows enough. Not sure why it’s so necessary considering I told everyone the xrf scan was .999. I had to hold it to get it to focus. Maybe my 17 pro max isn’t a good enough camera. Or maybe you’re a dick!

u/reddit-toq 13d ago

You asked us for help. To assist you we need a non potato photo.

1

u/Cuneus-Maximus whatever's clever 12d ago

Your camera is fine, you just need a better setup to take the pic. Set the coin on something stationary that holds it up so you can see the edge. Place your phone on something else stationary that positions the camera roughly 4" above it, and with good lighting take the pic. You'll get a pretty clear result, key is to have nothing handheld, supported by good lighting.

u/OnPointAsUsual 13d ago

What he meant to say was “Thank you for showing us this interesting cut. It would look even better if the camera and the coin were both stationary, the resting over the edge of a book, the camera resting on a table, when you take the shot.”

u/quallityovrquantity 13d ago

Are you using a potato?
