Guam Quarter Sounds Like Silver

It's been plated. Denver mint doesn't handle precious metals so they wouldn't be receiving silver planchets, and yeah the mint isn't lax on silver and gold inventory. A whole lot of stuff would have to go wrong from inventory exchanges between mint branches for something like this to happen at the mint.

More than likely though it's platinum plated though since that's the most common thing for the marketers to do, either gold or platinum plated regular quarters then sell them for $5 or $10 each to the unsuspecting for big profits.

On your edge pictures you can see the copper/clad line under the plating showing through because it was poorly plated.

All in all though it would be next to impossible for something like this to happen at Denver or Philidelphia. San Francisco could do it, but it would be the silver proof and totally normal to happen there.

Ok thanks for info. Yea the reason I took note was because it was Denver mint and I knew it shouldn't be precious metal my only thing is why it wouldn't weigh more than normal if it was plated but anyway I dont guess it matters I got my question answered as to why it didnt sound normal bouncing off of the counter so thank you all for all the help and for the tissue test info, I'll keep that in my arsenal.
