Hello huffmnd, I do not have any books on them, nor am I versed on what the values of different ones are , if I am comfortable with the price of one when I see it, I will buy it. I like them well enough, but I do not go out of my way to look for them. Looks like you picked up some pretty nice ones. I believe the ones with figures on the handles are the more desirable, but i am also sure that the names of certain ones are real bell ringers as well.huffmnd
