Too many pennies making my head spin!!!

I bought an estate about 7 months ago.
I have about 300-500 pounds of copper pennies.
Most are in tubes and dated.
Some tubes full others not full.
My dilemma is this,
Do I dump them all together to get a count?
Do I leave them in tubes and have no clear idea of how to weigh them because of the full and not full tubes.
I also have tubes and rolls of newer pennies that mean nothing to me but are dated.
Do I just take these to the bank and pay down my mortgage?
I also have a list of BU red pennies listed here
