It's most likely Galena (lead ore). Due to it's appearance, weight and color and is native to Pa.
Galena is one of the most abundant and widely distributed sulfide minerals. It crystallizes in the cubic crystal system often showing octahedral forms.

Pyrite was my first thought. However pyrite is a brassy gold color and Galena is the white bronze color as the OP described.
I can see where the confusion comes from as they both share the same shape and general appearance.
Easy to do a streak test to be certain. Pyrite will leave a greenish black or brownish black streak while Galena will leave a lead grey streak.
Flyadive ...Please let us know the outcome of the streak test.

Cool mineral sample whether galena or pyrite. I vote pyrite, but I have been known to be wrong before. No really, there was this one time when...

I do believe you have some Marcasite after pyrite there. http://www.mindat.org/min-2571.html

If it's Marcasite it will streak dark grey to black.
It could be any of the ones suggested above . I've found Pyrite that is silver
in color ...... I've also found the white Pyrite ( Marcasite ) like AB is talking about.
I've found Galena as well but not any that looked like that . But it is possible .
If you don't mind a booger on your piece you could streak it like GG says , but
a simple streak test based on the color of the dust "can" also be deceptive .
Just going by the pics ...... I'm gona guess Pyrite .

Ok...OK after some more research I am going with my first thought of Pyrite before I changed to Galena.
That is unless the streak test proves otherwise.
I knew i should have gone with my first impression....

To say it is pyrite is not saying that it is all bad! When you check for the rocks most often associated with gold, other than quartz, you will find out the three most common will be pyrite, arsenopyrite, and chalcopyrite. Arseno = arsenic..... chalco = copper. Remember this! TTC
