Which is why eBay is such a drag. 99% of this material needs to be melted which would be good for the environment and good for numismatics. With everything priced at 99p it sets the bar for people's expectations on price.
The world has a long way to go before there is a shortage of low grade material. I know I send tens of kgs to the pot every year and that is just a drop in the ocean. In fact, it makes you wonder at which point it is worth not melting. A while back I acquired a virtually full run of bronze pennies (missing 1869, 1870, 1926ME and 1950), mostly in fairly dire condition with the best Vicky no better than fine. Given the undesirable state of most, I bulked them up with a load of across the board 20th century to get rid of a few kilos, it had no bids despite only asking for scrap + fees + shipping + 10% as a starting price. My scrap man was happy to do a BIN with no time wasting eBayer to worry about.
I would have no hesitation in limiting things to one relist before scrapping, or just cutting out eBay altogether as future policy. Sure I'll check for the odd obvious rarity, but that aside it really isn't worth the time and effort. A washer for 99p including postage is a waste of time for everyone. With the cheapest shipping method possible, after fees it leaves 11p to be divided between the scrap metal value, packing and cost of getting it to the post office. The cost to the environment is considerably greater than 11p.
