I had them mixed together in 1 Lb. bags, will have to resort them. Will put the ones with the gold ring under can together and those with just gold pins in another bag. Thank you mechanic, Gold Forum looks like those guys might be best place for these transistors. I had noticed the ring before, but after reading some post in Gold Forum going to take a better look! Opened up a box of boards and have already found something I didn't see before. Some of these transistors have a gold ring, but no gold pins (tin/guessing). Also now going to look closer at crystal oscillators, some of those have gold pins. Goes to show, have to look good & read more.
