Hiawatha is nice looking and probably worth the $150 if it's a 26" model.
The Firestone Huffy is a base model I would guess (classicfan1 would know more about it).
Because it is the base modle with no chrome accent on the chainguard and no chrome rear rack stays...value in my opinion is $100. If the battery tray is in good shape (the bezel seems to be barely mounted) then I'd add $25 to it.
Just my opinion of course.
Go in at $175 for both and offer no more than $250 for the pair.
