My First Silver? [Updated: NO!!!]

I am fairly confident I broke every coin rule tonight.

Ok, so that unknown coin about the size of a quarter?  Well, it didn't want to clean up.  But after seeing that "R" stare at me, I HAD to know!  I seriously thought this was just a punch-out from an electrical box until that "R" glared at me.  So I tried to clean it with water some more.  Nothin'.

So I tried flaking off the pieces of rust with my finger.  They flaked, but I feared I was losing some valuable coin!  But I just had to know!  I searched high and low for some sort of acid (a big no-no, I'm sure), but I had none, so I just threw some hydrogen peroxide on the coin (that did nothing).  I tried taking a wire brush to the side without the "R" (again losing valuable pieces, I'm sure), but that didn't help.  I had what appeared to be a Girl Scout cookie in front of me...now missing a piece because I also slammed the coin against concrete trying to get some of those surface rust pieces to fall off.

After smashing it into the ground!  A piece chipped off.  :(

Well, after all of that, I did find something!  But it only quickens me to think that this may in fact have been my first silver...

Notice the similarities between a modern-day quarter and the now-visible letters on the coin behind it.  But notice one VERY important difference...the top left of the "R."  Today's quarters are have a smooth edge, but the Standing Liberty had a little flare on the "R"!  Agh, could it be?!

It took me FOREVER to even find these letters.  But the top left of the "R" flares on the old coin!

I checked the back of the Standing Liberty...right there in the middle is the "R" for E PLVRIBVS VNVM, in a lower position than on current quarters.  What is more, when I line up the current quarter with the old coin, it appears that the "B" is out of place with what I think is the "B" on the old coin.  But a quick glance at the Standing Liberty shows exactly why:  Liberty's head separates the "B" and the "E."  Agh, could it be?!  Did I find a Standing Liberty?!

The "R" flares!

The capital "R" would match the "R" that stared at me!

I have been ever-so-excited to find my first silver, and I don't even get the joy of knowing if I found it or not!  This is not how it was supposed to be!!!  Agh, it's still killing me!!!  The unknown of it all!

[EDIT:  After much scrubbing, excitement, foolish cleaning, and research, I have learned that this "coin" is in fact NOT silver.  After writing this post, I did some more research.  The test was simple.  I walked over to the fridge, grabbed a magnet, and put it up to the coin.  The coin stuck to it.  I then went over to my pile of other coins found and learned that no other US coin (outside of the 1943 steel penny) is magnetic.  This could have saved me a night of cleaning and staring!  Now...does it really say LIBERTY or am I just hoping it does?!  That's the part that doesn't make sense!  Those letters seem to line up...if they are letters?!]
