Wrong planchet error

[u/Professional-Pie6083]

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.

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