What would be a fair starting price for this item?

Hi guys!

 

I recently acquired these items at what I think is a pretty good price, but I would rather resell them in order to buy more appropriate items for my own collection. I don't know too much about them, but they are in excellent condition! They are apparently a 1951 booklet range.

 

Thanks for the help!
