I'm fairly new to strike collecting. I got hooked a little more than six months ago after moving to Reno. I kind of make Sierra Sid's my second home LOL. I find the info on this board invaluable and thank you all for a great site. I have a couple questions as to some of the terminology I see here, though. What constitutes an error in a strike? What is "rotated die"? What is "coin aligned"? "Medal aligned"?
