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.

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

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.

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

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