Did you have a chance to look at the coppercoins site I posted? All the info is there. Here's a edit; post #10 is a -003 post #11 is a -003 post #12 is a -008 At least that's how I see it.
Number 2 looks like DDO-3 Number 3also looks like DDO-3 But the pictures could be a little better lit. I can't tell what #1 is, the one you left unumbered in the post.
Keep in mind that there are subtle differences and i am going by the pictures. The way the groove on the base of the 2 is situated is different on #3 and #8. Both the coins pictured and mentioned aove have the groove in the base of the 2 in a way that corresponds to DDO-3 .
Here the link to number 8 http://www.coppercoins.com/lincoln/diestate.php?date=1972&die_id=1972p1do008&die_state=mds
