Thanks to everyone who responded and the nice comments!
So I have been very, VERY slowly chipping away at this album. Lol. Honestly, mostly due to the fact that half dollars are usually pretty hard to find. I did purchase a few from my local coin store.
I was actually lucky enough to come across two rolls of them yesterday at my credit union. No silver coins, though. I would actually be interested in possibly purchasing some of the silver proofs from the 60's eventually. I'd have to add a blank page somewhere.
First page is almost complete. Missing those special 1964 coins.

Second page is getting there. I found these all in circulation.

These too.

Bought these. Funny how much different the strike looks.

This was purchased when I bought a mint set. It's quite lonely all by itself lol

The
Kennedy half dollar (and halves in general) are pretty cool coins. I like the size of them and it feels quite nice squeezing them into the ports, unlike a lot of smaller coins.
That said, I wish I could find more halves around easily. I would request my credit union to order me a box, but uh, 500 dollars is a lot of money!
