best price

since money is more important to me in my present situation then time. I have started to tear the class 2 (small ac/dc transformers apart to get the pure copper out of them, rather then sell them for motor price (.25) per lb. I have question. the shiney bright hair sized copper wire , what class is it #1 #2 or something else, also on some of the transformers there is one spool of "hair" wire and one spool of larger wire looks to be about 18 guage should I sell these seperately. also has any one used muratic acid to clean the varnish and or paper and glue from these wires, or what ha been successful for you. thx
