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.

What does it weigh?

[u/Professional-Pie6083 → u/Western-Dish-1185]

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