Neat cards!
Personally, I wouldn't grade them.
Also, when it does come time to sell these, the customer likely won't be someone putting together a mid-grade set that needs the cards individually, want them holdered, put them in set-order, never to put the backs together again.
The customer instead will buy them due to the backs fitting together and they will want to put the backs together raw to see how well they match, etc. I don't think the grade will matter to them as much.
just my preference and 0.02, good luck w/your decision!
