Just curious -- if you were choosing between a sunburst-cancelled chipco and a notched-cancelled chipco, which would you prefer to add to your collection? (Assume that a non-cancelled chip wasn't available.)
a. sunburst
b. notched
c. about the same / no preference
d. no interest in any cancelled chips.

As examples, see the sunburst design, followed by the notched example. (I'm assuming that the sunburst design is not part of the final design, though I'm not sure.)
