High Resolution images of new late die stage of 1954-S LWC RPM#6
I have found an example of 1954-S RPM#6 which is later than stage L, the last stage listed by CONECA. This new stage has a large die chip out of the 9 of the date, where stage L has no evidence of a chip even beginning to form. This likely means there are intermediate stages after L but before this coin. In addition, this coin shows a change to a new reverse die, so is a new die marriage as well.

I've posted this coin to the CONECA Attribution forum using their new process.
