Mother Lode

Went to my dump bank, and there was a person in front of me who had rolls of pennies, nickels, and dimes.
I said I would buy them, since I am a coin collector. The total was $113.
From the 9 dime rolls.. 4 silver roosies
From the 6 nickel rolls.. 4 CA nicks (1 Ni) & 4 Buffs 1934, 1937, 2 dateless..
From the 112 penny rolls... ONLY $7.23 in ZINC! That is 87% COPPER! And, for some strange reason...
...about 70% of the copper cents were 1975 in AU/BU Condition!
I have no idea why, but I am like OH YEAH!
Any ideas of what to do with the 1975s?
