Just for one scrap dryer you won't get too much at the scrap yard.
For one scrap dryer you may only get $1.00 or $2.00 if that's the only scrap you have when you haul the dryer in.
If you remove the copper wire from the dryer you could sell the copper separate but it still won't bring even another $1.00
It would either be best to just sit it out on the curb for someone else to come and take away or hold onto it until you have some additional scrap.
That is unless you just want it gone and recycled then it may still be worthwhile for you to drop it off at the scrap yard just to get it out of the way.
But you won't make much out of one scrap dryer.
