should i keep it sell it or even trade it

Yesterday I finally got the last coin to finish out my NGC PF69 Statehood Quarter Set and almost half way done with my NGC PF70

Statehood Quarter Set. I just started my PF70 after I got my territories PF70 and I plan on getting the National Parks in NGC pf70 when they come out also as well as trying to get the quarters before the statehoods.

So do you think I should do the same with the PF69 or should I get rid of it (sell/trade) or leave it as it is?

I have no idea right now just having fun trying to build more sets and hopefully get more sets to 100%. If I do get rid of them I think as a whole might be the best way. I would trade rather trade them than sell them.

Also Just purchased a set of the 2010 presidential NGC PF70 in which I have to get another one since I am trying to build 2 sets
