3 part gold pins question

very good question about the pins from ribbon cables. I was told awhile back to keep all pins separated by type. So I now have small (maybe an 8 oz ) Tupperware full of them separated by type of pin. At some point I will organize they types by how much gold is on them. Like you I have found some, maybe 5% that are entirely covered. I have not talked to an actual refiner about it. From what I have seen on eBay most of the pins there are all consistent by type and coverage. I'm just in the hording stage so I have only done a minor amount of research on the selling end. I got a craft box that has one big box with a lot of tiny boxes and keep the pins as separated as I can. when they don't fit in the little boxes they go in small Tupperwares. I don't want it to sound like I have a giant scrap gold collection but I have been doing enough that it would be a sweet not to have to sort so much or go back and sort even more.
