To me the 1968-S LMC is a tough roll to hunt in my opinion, after hunting I don't know how many rolls finally found a DDO. WDDO-003. Notice the small vertical bars extending north from LI of liberty. adding to the collection. Just wanted to share.
looking at then real quick with the loop looks like maybe 3 or 4 different stages or progressions. But very minor differences in length and other slight differences.
Going through a roll of 1972 D LMC found 10 of the exact die crack (spike head). I usually do keep spike heads but it was cool to find 10 of the same. Just sharing.
