Prices look good to me, Frank! I think you'd have to be nitpicking to find a cheaper place to buy these on sale like that.
I'm not sure about collectible. I guess it depends on what you are collecting. Nosferatu is a Curt Hanson introduction. I think a lot of people like to collect Curt's plants, so this would be a good time to get this one, maybe.
Lavender Blue Baby was used as a parent on seeds I bought on the LA, and the kids look awesome.
If you are looking at blue eyes, it seems to be a good one to have. I just checked, 313 child plants. (yikes! that's crazy!)
If you mean historically collectible, Rocket City is an intro by Hardy (what is his first name?) from 1967, which makes it a really old Tet. It's known parent is Crestwood Gold, which is an intro from Fay-Griesbach from 1963. I think all three of those names are Tet pioneers. If you are into historical daylilies, RC might be pretty cool to own.
