"Just a quick correction in case someone else references this thread. A quarter and a dime actually weight 35 + 87.7 = 122.5 grains. A quarter and a penny weight 126.08 grains."

Whoops, yep.

"I would not trust a penny because they keep changing the composition."

Any penny minted in the last 5 years was minted to current standards as listed on the Mint's website.

I think prior to 5 years ago they were a little heavier, but not much.
