They look like older Cage coils, if they are, they are good. Also seeings how it is Tom's B.P. selling them, they are more than likely a quality product. I wouldn't worry about spending 50-75 on them, shipping says its $39, a little high in my opinion. The only problem is that a new set only costs about $160 from BC and they only charge what they get charged for shipping. If you do bid on them, don't spend more than $75 otherwise you might as well order a brand new set.
