Well heck ! You know I look at Variety Vista and in their pics it's hard for me too see what they are looking at !!
To the inexperienced eye machine doubling can look similar to die doubling, but it doesn't take much practice to see the difference. Spending a little time looking at true doubled die coins helps enormously. http://www.coinbidders.com/Strike Doubling Flyer - PDF.pdf
VM, I've been trying on Variety Vista. But in their pics it's hard to tell what they are looking at. Paddy gave me a site called Lincolnsource which has better pics but even some of those look flat to me. Well practice makes perfect they say, as long as you guys can put up with me ! Thanks for all the help again people !
Try www.coppercoins.com. Go to the left column and scroll down to "die variety search", click, fill out info, click and get the list. If under a photo they have a die state...EDS ( early), MDS, or late die state click for large photos, such as this of 1995D DDO 003. http://www.coppercoins.com/lincoln/diestate.php?date=1995&die_id=1995d1do003&die_state=eds
