    I picked up these from a collection recently. I know they are common sets, but I've heard there can be errors on certain sets? RPMs, etc. Any advice appreciated.

    Check the 1970 set for the Lincoln cent small date.

    Highly unlikely, but I guess you could check for the 1968 no S dime? Or the 1971 no S nickel? Hope springs eternal :)

    Look carefully and use your red book to help determine varieties and errors.

    The best place to look for Proof errors/varieties that I can think if right now of is the Cherrypicker's Guide Vol. 2.
