1972 ddo #4-0-1

Cherrypickers guide states it is rarer than ddo#1 which is the one everyone knows of. I found one that is in xf-au.Anyone have currect price for this coin.I am going to sumbit it to anacs,along with a 3-0-1 and hopefully a few more by the time I get finished going through the ones I set aside to check.
Do sets contaning all examples of the ddo for 1972 have a market? Any thoughts?
