I picked up a couple hemenway 42s last weekend too. Are they worth anything more than $1? I read that they made over a billion insulators. Cool looking with nice color.

Most aqua or clear versions are extremely common and have no collector value. Look for embossing errors, amber swirls, unusual qualities like the extra-long drip points posted above. Florida had some lines using the smooth base version, too, and those can sell in the 20 dollar range.
But even if they're common, no reason you can't enjoy having some old insulators on your shelf.

nym9nyj7,
Honestly, i really don't know. But I do know that is a cd 102, and I'd guess it was used on telephone lines?
I'm sure Bill or others here could provide you with a ton of information about it.....so I'll sit back and learn with you!

Yes, the pony on the right is a telephone style, typically used on local lines. That one's a CD 106 but the CD 102 was used the exact same way.
The middle is a Hemingray 40, usually used on telegraph lines. Western Union made this their standard style from 1911 to somewhere around 1921.
The left side is what collectors usually call a "Johnny ball" but I have no idea where that name came from. They typically were used as a guy wire strain, like the photo linked here:

Imagine if someone tried to support a pole using a solid wire anchored to the ground. It's not too hard to see that it would give the electricity a nice straight path to ground, creating shorts in the line. So the strain insulator (or Johnny ball) interrupted the guy wire. If you look at a modern-day pole, you'll probably see a porcelain strain-type insulator on the guy wire.

Sparrow - I meant to say "left" my bad! (At 26 I still seem to have problems with this whole left and right thing!!! 
Billin, thanks for all the good info. That's pretty cool. I've never come across one of those tiny ones before. I'll have to keep my eyes pealed...
