As you guess, the pedals are Shimano - you can make out the base of the logotype on the picture along with the FD A550 model number.
I love the idea of them going in the "recycle" box, destined for a life being pedalled backwards.
I'd wager that the toeclip fixing pattern is sufficiently rare for them to be worth something with anyone with similar Shimano models. If only I liked Shimano stuff...
