I'd second that . See there are 2 thoughts to selling copper with Ebay
One is for future investment so your price can be kinda over spot but low enough for the buyer to dream of the day they resell .
For arts and crafts it needs to look well organized . Your picture looks as investment type selling but the price is way off spot .
Probably if you could get some spools like for sewing thread & make a nice looking copper wound spool you will get your price.
Ive sold plenty of copper on Ebay just not lately Ive got a 100% rating
