Justification works for me. Have fun buying them, guilt is a made-up construct. I sell some coins/stuff I don't care about any longer or get a deal on what I'm buying to justify it. But more than anything, enjoy the purchase and the new coins!
Because my CSA (Coin Savings Account) is about 1% of yours, I don't have any of the ones you listed, except for this one! I was lucky enough to get it (with OGP and COA too!) for only $15 bucks! I did notice that dark clouds are obliterating the sunrays trying to break through. I guess even the designer knows about our partisan bickering. Most people can't identify the Statue of Freedom or know where it is (atop the dome of Capitol Building). Me included. Wished I had known about this during an old school trip to visit. I would've looked for it, to see it in real life.
I love the early commemorative set and it is a challenge to collect. It took me 15 to finish the set and I may want to upgrade a few of them early commemorative are a fun set and you made a wise choice.
I think prices for the classic commems are very low right now, historically, so this would seem to be a good time to pick up some choice examples. Be picky.
