wanted: pre 1976 topps cards #300, #666

have a collection of cards #'d 300, 800, and 666. this is a fun collection so I am not in need of mint cards for it. I would like to trade for these. my trade stock of vintage if very slim and few are in decent condition but feel free to ask for them. creases are ok, bent corners, just don't want it torn and taped back together (unless its like a $100 or better then that may be an option). if you have a mint one I MAY be interested but I really doubt I can trade for it, but feel free to let me know what you have anyway and what you would like in return.

here is a list of what I need:
